There are 900 creatures in a zoo as per list given below:
Represent the above data by a pie chart.
Total number of creatures $=900$
Central angle of each component $=\left(\frac{\text { number of creatures in each type }}{\text { total number of creatures }} \times 360\right)^{\circ}$
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 $60^{\circ}, 160^{\circ}, 70^{\circ}, 50^{\circ}$ and $20^{\circ}$.
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.
