The numbers will be represented on the pie chart based on their totals out of 360 degrees.
How to draw the pie chart ?
First, find the total of the figures :
= 5 + 20 + 30 + 25 + 10
= 90
Then find the degree measures for each:
= 5 / 90 x 360
= 20 degrees
= 20 / 90 x 360
= 80 degrees
= 30 / 90 x 360
= 120 degrees
= 25 / 90 x 360
= 100 degrees
= 10 / 90 x 360
= 40 degrees
Then use these degrees to demarcate the sections on a pie chart as shown attached.
