To draw circle diagram for the given data, find the square root of the production of cars and dividing it by 160, we get the radius of circle for the production of different years.
We prepare the table as follows :
| Year |
Production of cars |
Square root |
Radious Square root 160 |
| 2012 |
25,600 |
160 |
160 / 160 = 1.0 |
| 2013 |
1,02,400 |
320 |
320 / 160 = 2.0 |
| 2014 |
1,60,000 |
400 |
400 /160 = 2.5 |
Drawing circles taking radius corresponding to production of cars in different years. Circle diagram is obtained as follows :
