In the time table of a school, periods allotted per week to different teaching subjects are given below. ?
$\begin{array}{cccccccc}\text{Subject}& \text{Hindi}& \text{English}& \text{Maths}& \text{Science}& \text{Social Science}& \text{Computer}& \text{Sanskrit}\\ \text{Periods allotted}& 7& 8& 8& 8& 7& 4& 3\end{array}$
Draw a pie chart for this data.

Answer 1

Total periods = 7 + 8 + 8 + 8 + 7 + 4 + 3 = 45
$\begin{array}{ccc}\text{Subject}& \text{Periods allotted}& \text{Central angle}\\ \text{Hindi}& 7& \frac{7}{45}\times {360}^{\circ }={56}^{\circ }\\ \text{English}& 8& \frac{8}{45}\times {360}^{\circ }={64}^{\circ }\\ \text{Maths}& 8& \frac{8}{45}\times {360}^{\circ }={64}^{\circ }\\ \text{Science}& 8& \frac{8}{45}\times {360}^{\circ }={64}^{\circ }\\ \text{Social Science}& 7& \frac{7}{45}\times {360}^{\circ }={56}^{\circ }\\ \text{Computer}& 4& \frac{4}{45}\times {360}^{\circ }={32}^{\circ }\\ \text{Sanskrit}& 3& \frac{3}{45}\times {360}^{\circ }={24}^{\circ }\end{array}$
The pie chart is as follows :
