Question

Steps to draw a pie chart

Answer 1

It is a circular graph which is used to represent data. In this :

● Various observations of the data are represented by the sectors of the circle.

● The total angle formed at the centre is 360°.

● The whole circle represents the sum of the values of all the components.

● The angle at the centre corresponding to the particular observation component is given by

● If the values of observation/components are expressed in percentage, then the centre angle corresponding to particular observation/component is given by

Answer 2

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



Step 2: Draw a circle using a pair of compasses 
Step 3: Use a protractor to draw the angle for each sector.
Step 4: Label the circle graph and all its sectors.
