Question

$\text{The data on religionwise division of 1080 workers of a factory are given below :}$

$\begin{array}{ccccc}\text{Religion}& \text{Hindu}& \text{Muslim}& \text{Sikh}& \text{Christian}\\ \text{Number of workers}& 450& 270& 255& 105\end{array}$

$\text{Draw a pie}\&\text{chart to represent the above data.}$

Answer 1

$\text{Here total number of workers = 1080}$

$\begin{array}{ccc}\text{Religion}& \text{Number of workers}& \text{Central angle}\\ \text{Hindu}& 450& \frac{450}{1080}\times {360}^{\circ }={150}^{\circ }\\ \text{Mulsim}& 270& \frac{270}{1080}\times {360}^{\circ }={90}^{\circ }\\ \text{Sikh}& & 255-\frac{255}{1080}\times {360}^{\circ }-{85}^{\circ }\\ \text{Christian}& 105& \frac{105}{1080}\times {360}^{\circ }={35}^{\circ }\end{array}$

$\text{Now (i) Draw a circle with a suitable radius}\text{(ii) Draw a horizontal radius}\text{(iii) Starting from this radius, draw sectors whose central angle are}{150}^{\circ },{90}^{\circ },{85}^{\circ },{35}^{\circ }\text{respectively}\text{(iv) Now shade the sectors with different colours or designs as shown in the figure.}$
