The document presents information about three types of curved plane solids: cylinders, cones, and spheres. It provides the definitions and key characteristics of each shape. Formulas are given for calculating the curved surface area, total surface area, and volume of cylinders, cones, and spheres using variables like radius (r) and height (h). Examples are given to practice applying the formulas to find missing values given certain known parameters.

3. Curved Plane Solids

4. There are 3 Kinds of Curved
Plane Solids
1. Cylinder
2. Cones
3. Sphere

5. Cylinder
• Cylinder is a closed solid that has two
parallel(usually circular) bases connected
by a curved surface.

and Surface Area

8. The Formula to find Volume of
Cylinder

9. Cone
• Cone is a dimensional geometric
shape that tapers smoothly from a
base (Usually flat and circular) to a
point called the apex or vertex.

13. SPHERE
• such as the shape of a round ball, which is in
two dimensions, a sphere is the set of points
which are all the same distance r from a given
point in space. This distance r is known as the
"radius" of the sphere, and the given point is
known as the center of the sphere. The
maximum straight distance through the
sphere is known as the "diameter".

15. The Formula to find Surface Area
• Surface Area : 4�r²
• r = √SA

16. The Formula to find Volume of
Sphere
• Volume of Sphere = 4 � r3

196,25 cm3 and the height is 10 cm. Find
The Radius,Curved Surface,And
Surface area.
2. Known that the radius of a cone is 7 cm.
And the height is 9 cm. Find The volume
of a cone.
