Various modes of transport used by 1260 students in a given school are given below:

Total number of students $=1260$

Central angle of each component $=\left(\frac{\text { number of students using that mode }}{\text { total number of students }} \times 360\right)^{\circ}$

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 $100^{\circ}, 70^{\circ}, 60^{\circ}, 50^{\circ}$ and $80^{\circ}$.

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.
