Pie Chart
Representation of data in a circle is called Pie chart.

Now that we have learnt about circles, let’s see how to represent a data in a pie chart. Look
at the given example. The table below gives information about the different flavours of ice
creams liked by different students.

Ice cream Number of students
chocolate 20
strawberry 10

tutti-frutti 15
butterscotch 10

vanilla 5

Step 1: Find the total number of students which is 60.

Step 2: The measure of a circle is 360°. So, we need to find out what part (angle) of 360°
each ice cream will cover. To calculate this, we use the formula:
Number of students who like a flavour
Angle covered = × 360°
Total number of students

Number of Remember
Ice cream Angle covered
students The measure of a circle is 360°,

chocolate 20 20 × 360° = 120° i.e., when you start from A

60 and move around the
boundary of the circle and
strawberry 10 10 × 360° = 60° again reach A, the angle
60 covered is 360°.

tutti-frutti 15 15 × 360° = 90°

60
butterscotch 10 10 × 360° = 60°

60

vanilla 5 5 × 360° = 30°
60

Total = 60
