To create a pie chart: 1. Draw a circle and mark its center. 2. Draw lines from the center to the edge to divide the circle into sectors based on data percentages. 3. Measure each sector's angle and label it to match its data label. A pie chart illustrates proportional data by dividing a circle into sectors sized according to data percentages. It is commonly used in business to visualize data distributions but can be difficult to compare across charts. Bar charts are often a better alternative.

1) 1) Create a pie chart of the subject likes of
the students of grade 8 B. frequency chart
given below.
subject frequency
Math 40%
Science 30%
SST 20%
Arabic 10%

3. 1) Solution:
example
2) Math:40%→40/100=4/10=2/5x360=144°
3) Science:30%→30/100=3/10X360=108°
4) SST:20%→20/100=8/10=1/5X360=72°
5) Arabic:10%→10/100=1/10X360=36°

7. • A pie chart is a divided into sectors,
illustrating numerical proportion. In a pie
chart, the arc length of each sector (and
consequently its central angle and area), is
proportional to the quantity it represents.
While it is named for its resemblance to a
pie which has been sliced, there are
variations on the way it can be presented.
The earliest known pie chart is generally
credited to William Playfair's Statistical
Breviary of 1801

8. • Pie charts are very widely used in the business world and the
mass media. However, they have been criticized, and many
experts recommend avoiding them, pointing out that research
has shown it is difficult to compare different sections of a
given pie chart, or to compare data across different pie
charts. Pie charts can be replaced in most cases by other
plots such as the bar chart.
