represents a part of a data set. These sectors may be mostly represented as percentage. This circle graph is

also called pie chart. To draw the graph we need to calculate the degrees for each arc or sectors. This is

done by multiplying percentage with 360 degree. Then with the help of a protractor the graph is drawn. This

circle graphs are very useful tool and explained by the following examples.

on red, 60 sitting on blue, and 60 sitting on green. Calculate the percentage and degrees of the

circle graph.

Percentage on red chair = 80/200 x 100= 40%; (40/100)360 =144°

Percentage on blue chair = 60/200 x 100= 30%; (30/100)360 =108°

Percentage on green chair = 60/200 x 100= 30%; (30/100)360 =108°

percentage and degree of the types of cars.

Percentage of Zen = 20/110 x 100 = 18.18%; (18.18/100)360 =65.45°

Percentage of Santro = 20/110 x 100 = 18.18%; (18.18/100)360 =65.45°

Percentage of Nano = 30/110 x 100 = 27.77%; (27.77/100)360 =99.97°

Percentage of WagonR = 40/110 x 100 = 16.66%; (16.66/100)360 =59.97°
