The document discusses the application of mathematics in popcorn packaging. It begins with an introduction to popcorn and its history. It then presents the objectives and sections of the project. Section A involves an experiment comparing the volume of cylinders made from paper. Calculations show that a cylinder with a larger radius holds more popcorn. Section B discusses finding the container shape from given materials that can hold the most popcorn volume. A cuboid is determined to have the greatest volume. In conclusion, different container shapes are compared and a cuboid is found to hold the most popcorn.
This document provides sample questions and answers related to various mathematics topics, including functions, quadratic equations/functions, simultaneous equations, indices and logarithms, and coordinate geometry.
The questions are multiple choice or short answer questions assessing skills like solving equations, graphing functions, finding inverse functions, and working with logarithmic and exponential expressions.
The answers section provides fully worked out solutions to each question in a clear format. This document appears to be a reference for teachers or students to use for exam preparation or review, with the goal of assessing conceptual understanding of core algebra and geometry topics.
The maximum value of y occurs when x = 4.
Plugging x = 4 into the equation for y gives:
y = -4sin60ยฐ + 80(4)sin60ยฐ
y = -4โ3 + 320โ3
y = 316โ3
So the maximum area is 316โ3 square units.

This document is a math project submitted by Teh Ming Yang for class 5C. It examines volume and surface area calculations for different shapes like cylinders and cones. Through experiments using cylinders made of paper, it demonstrates that cylinders with larger radii hold more popcorn even if they are shorter in height. This is because radius has a greater impact on volume than height due to how it is calculated in the volume formula. The project also explores maximizing volume for a given surface area, comparing cones and cubes. The objectives are to apply math concepts to solve problems and appreciate the importance and beauty of mathematics.
1. The document discusses the relationship between temperature and pressure in two thermometers using equations. It provides examples of calculating unknown temperatures and pressures.
2. It examines the readings of nitrogen and hydrogen thermometers at the boiling point of water and finds a small difference in the measured pressures.
3. Several examples are given of calculating temperature changes, length changes, volume changes, and density changes in various materials based on their coefficients of thermal expansion and temperature changes.

Part 4 adjusts the family's budget to afford the TV and includes the student's own budget after getting a job. The conclusion reflects on learning about indexes in daily life.
This document contains 8 calculus word problems involving finding maxima and minima. The problems involve topics like:
1) Finding numbers that maximize a product given their sum.
2) Finding fence dimensions that maximize enclosed field area given fixed fence length.
3) Finding minimum tin sheet area to make a closed cylinder of fixed volume.
4) Finding poster dimensions that minimize total area while meeting margin requirements.
5) Finding window proportions that maximize light admission given fixed perimeter.
6) Finding quantity that minimizes product cost given a cost function.

8) Finding percentage volume of largest inscribable cylinder to cone volume.
This document summarizes an experiment analyzing lift on a rotating cylinder. A 1.5 inch diameter hollow polypropylene cylinder was tested in a wind tunnel at various rotation speeds (RPMs) and air velocities. Experimental results showed that increasing the non-dimensional speed ratio (ratio of cylinder rotation to air velocity) increased the coefficient of lift per unit length, though not as high as potential flow theory predictions due to viscous effects. Results were similar to a previous 2001 experiment by Aoki and Ito but slightly different likely due to differences in cylinder/test section setup. Overall, lift per unit length increased with higher speed ratios for the Reynolds number range tested.

Biology - chapter 6 ( ruminant and rodent ) form 4..Nurul Izzah
ย
Ruminant animals have a specialized four-chambered stomach that allows them to digest cellulose. In the first chamber, the rumen, plant matter is broken down by microbes into liquids and solids. The solids are regurgitated and rechewed while liquids pass to subsequent chambers for nutrient absorption. The fourth and final chamber, the abomasum, is similar to non-ruminant stomachs. This specialized digestive system allows ruminants to break down tough plant fibers in their diets.
1. The story follows Kertala Sari, who was sent by the Majapahit Kingdom to attack Melaka and kill its king and admiral in revenge for his father's death.
2. In Melaka, Kertala Sari stole treasures from wealthy merchants, storing them in Bukit Cina. He was later killed in a duel with the admiral.
3. The admiral was praised for his defense of Melaka and gifted a share of the recovered treasures, which he gave to the poor. When news of Kertala Sari's death reached Majapahit, the patih plotted to send another warrior to kill the king and admiral of Melaka.

INTRODUCTION TO
POPCORN
Popcorn is a type of corn that expands from the kernel and puffs up when heated.
Popcorn is able to pop like amaranth grain, sorghum, quinoa, and millet. When heated,
pressure builds within the kernel, and a small explosion (or "pop") is the end result. Some
strains of corn are now cultivated specifically as popping corns.
There are various techniques for popping corn. Along with prepackaged popcorn, which is
generally intended to be prepared in a microwave oven, there are small home appliances
for popping corn. These methods require the use of minimally processed popping corn.
A larger-scale, commercial popcorn machine was invented by Charles Cretors in the late
19th century.
Unpopped popcorn is considered nonperishable and will last indefinitely if stored in ideal
conditions.
Depending on how it is prepared and cooked, some consider popcorn to be a health food,
while others caution against it for a variety of reasons. Popcorn can also have non-food
applications, ranging from holiday decorations to packaging materials.
5. 4
HISTORY OF POPCORN
Popcornwas first discovered thousands of years ago by Native Americans. It is
one of the oldestforms of corn: evidence of popcornfrom 3600 B.C. was found in
New Mexico and even earlier evidence dating to perhaps as early as 4700 BC
was found in Peru. Some Popcornhas been found in early 1900s to be a purple
color. The English who came to Americain the 16th and 17th centuries learned
about popcornfrom the Native Americans.
During the Great Depression,popcornwas comparatively cheap at 5โ 10 cents a
bag and became popular. Thus, while other businesses failed,the popcorn
business thrived and became asource of income for many struggling farmers.
During World War II,sugar rations diminished candy production, causing
Americans to eat three times as much popcornthan they had before.
At least six localities (all in the Midwestern United States)claim to be the
"PopcornCapital of the World": Ridgway, Illinois; Valparaiso, Indiana; Van Buren,
Indiana; Schaller, Iowa; Marion, Ohio; and North Loup, Nebraska. According to
the USDA, most of the corn used for popcornproductionis specificallyplanted
for this purpose;most is grown in Nebraska and Indiana, with increasing area in
Texas.
As the result of an elementary schoolproject, popcornbecame the officialstate
snack food of Illinois ,U.S.A.

SECTION A
QUESTION 1
For this activity, you will be comparing the volume of 2 cylinders created using the same sheetof paper.
You will be determining which dimension can hold more popcorn. To do this, youwill have to find a
pattern for the dimensions for the containers.
Materials : 8.5 x 11 in. white paper, 8.5 x 11 in. colored paper, tape, popcorn plate, cup, ruler.
1. Take the white paper and roll it up along the longest side to form a baseless cylinder that Is tall
and narrow. Do not overlap the sides. Tape along the edges. Measure the dimensions with a
ruler and record your data below and on the cylinder. Label it โCylinder Aโ.
2. Take the colored paper and roll it up along the shorter side to form a baseless cylinderthat is
short and stout. Do not overlap the sides. Tape along the edge. Measure the heightand diameter with a
ruler and record you data below and on the cylinder. Label it โCylinder Bโ.
8. 7
DIMENSION CYLINDER A CYLINDER B
HEIGHT 11 8.5
DIAMETER 2.6 3.4
RADIUS 1.3 1.7
QUESTION 2
Do you think the two cylinders will hold the same amount? Do you think one will hold more than
the other? Which one? Why?
ANSWER:
The two cylinders will hold the different amount. Cylinder B will hold more than Cylinder A. This is
because the radius of Cylinder B is longer and this make the volume is bigger than Cylinder A.
Although the height of Cylinder B is shorter than Cylinder A, but this does not affect much
compare the affect of different in radius.
QUESTION 3
Place Cylinder B on the paper plate with Cylinder A inside it. Use your cup to pour popcorninto
Cylinder A until is full. Carefully, lift Cylinder A so that the popcorn falls into Cylinder B.Describe
what happened. Is Cylinder B full, not full or over flowing?
ANSWER:
Cylinder B is not full. There is still space in the cylinder for more popcorn.

QUESTION 4
a) Was your prediction correct? How do you know?
b) If your prediction is incorrect, describe what actually happened
ANSWER:
a) Yes, the prediction is correct. It is based on the formula, volume of cylinder equals to .
According to the formula, radius, r has more effect than height, h since radius, r is squared.
Thus, the Cylinder B with greater radius, r have the greater volume, V than Cylinder A.
b) Cylinder B has a greater volume than Cylinder A.
QUESTION 5
a) State the formula for finding the volume of a cylinder
b) Calculate the volume of Cylinder A.
c) Calculate the volume of Cylinder B
d) Explain why the cylinders do or do not hold the same amount. Use the formula for the formula
for the volume of a cylinder to guide your explanation.
ANSWER:
a) ๐ฃ = ๐๐2โ
b) ๐ฃ = ๐๐2โ
= ๐ ร 1.3 ร 1.3 ร 11
= 58.4 ๐๐๐โ3
c) ๐ฃ = ๐๐2โ
= ๐ ร 1.7 ร 1.7 ร 8.5
= 77.2 incโ3
d) The cylinders have different radius and heights, so the volumes are different.
10. 9
DATA AND OBSERVATION
๏ง The cylinder with have the greater radius and
diameter will have the greater volume
๏ง The radius of Cylinder B is greater than Cylinder A.
๏ง The volume of Cylinder B is greater than Cylinder A.
๏ง So, Cylinder B holds more popcorn than Cylinder B.
DIMENSION CYLINDER A CYLINDER B
HEIGHT, incโ2 11 8.5
DIAMETER, incโ2 2.6 3.4
RADIUS, incโ2 1.3 1.7
VOLUME, incโ3 58.4 77.2
QUESTION 6
Which measurement impacts the volume more: the radius or the height? Work through the
example below to help you answer the question.
Assume that you have a cylinder with a radius of 3 inches and a height of 10 inches. Increase the
radius by 1 inch and determine the new volume. Then using the original radius, increase the height
by 1 inch and determine the new volume.
ANSWER:
CYLINDER RADIUS HEIGHT VOLUME
ORIGINAL 3 10 282.7
INCREASEDRADIUS 4 10 502.7
INCREASEDHEIGHT 3 11 311
Which increased dimension had a larger impact on the volume of the cylinder? Why do you think
this is true?
Increasing the radius increased the volume more than increasing the height. This is because the
radius is squared to find the volume, which increases its impact on the volume.

Shape of containers that give the most popcorn reflect the maximum volume. From the activity
earlier, I found that increasing the radius increased the volume more than increasing the height.
This is because the radius is squared to find the volume, which increases its impact on the volume.
From the calculations, it has been found that cuboid can be filled in with the most amount
popcorn. These means that cube is the container that can be filled with the least amount of
popcorn. Randomly, surveying at the movie theatre , no cube or cuboid shapes can be found.
Therefore, in this case, the cuboid was the most preferable container that can have the most
popcorns.
๏ผ You are the popcorn seller, what type of container would you look for?
If I was the popcorn seller, I will look for cube shape container. It is because the least popcorns
will be in. So, I will get the most profit for my sale. Furthermore, it is cute and simple shape.
๏ผ You are the producer of the containers, what type of container would you choose
to have the most profit?
If I was the producer of the popcorns containers, I will look for cylinder shaped
container. It is because this shape is the easiest production and it takes less effort and
also no time consuming to produce.
