## 14.5 Pie charts:

A pie chart is a graphical representation of how many individual parts contributes to the total. A pie chart is a circular chart divided into sectors. In a pie chart, the arc length of each sector is proportional to the quantity it represents.

### Constructing Circle Graphs

Study the following steps of constructing a circle graph:

Step 1: Calculate the angle of each sector, using the formula

Angle of sector = Frequency of data x 360o/Total frequency

Step 2: Draw a circle using compasses

Step 3: Use a protractor to draw the angle for each sector.

Step 4: Label the circle graph and all its sectors.

Example: in an medical survey it was found that, in year 1 there were 10 cases of malaria, in year 2 it increased to 15, in year 3 there were 23 such cases and in year 4 again a rise of about 20 cases. Draw a circle graph to represent the number of cases per year.

Total number of cases: 10+15+23+24 = 72

In year 1: 20 x 3600 = 500

72

In year 2: 15 x 3600 = 750

72

In year 3: 23 x 3600 = 1150

72

In year 4: 24 x 3600 = 1200
