Question:
The data on religion wise division of 1080 workers of a factory are given below:
Draw a pie chart to represent the above data.
Solution:
Total number of workers $=1080$
Central angle of each religion $=\left(\frac{\text { number of workers in each religion }}{\text { total number of workers }} \times 360\right)^{\circ}$
Calculation of central angles
Construction of pie chart
Steps of construction:
1. Draw a circle of any convenient radius.
2. Draw a horizontal radius of this circle.
3. Draw sectors whose central angles are $150^{\circ}, 90^{\circ}, 85^{\circ}$ and $35^{\circ}$.
4. Shade the sectors so obtained differently and label each one of them.
Thus, we obtain the required pie chart as shown in the figure below.
