To find the angle of each sector
Total of data corresponds to 360o.
Let xo = the angle at the centre for item A, thenThe data given in example 1 can be used to draw a pie graph.Calculation of Angles
Food:
Angle at centre
= 150oRent:
Angle at centre
= 40oSimilarly we can calculate the remaining angles, and the total of angles column should always come to 360o.
A survey was conducted to find out the consumption of various brands of soap. The results of the survey are given below:
(i) Soap Cake:
(ii) Soap Powder:
(i) Using the information given in the table for soap cake, draw a pie chart.(ii) Using the angles in the pie chart for soap powder, complete the table that follows:
(i) Draw Pie Chart
Total of the items = 100
A. Angle at centre= 216o
B. Angle at centre= 72o
C. Angle at centre= 54o
Other Angle at centre= 18o
(ii) Complete the table
For P,
Similarly
Same way we can calculate the values of R, S and others.
R = 25%, S = Others =
