Question

There are 10 children in class 5 out of 240 children in a school. Calculate its central angle when represented in a pie chart.

• A. It must be red
• B. It must be white
• C. May be red or white
• D. Nothing can be said about the colour

Answer 1

The correct option is C

May be red or white

Number of children in class 5 = 10

Total number of children = 240

Central angle = $\frac{10}{240}\times {360}^o$

= ${15}^o$
