Description: To get a piece of particular information from the given data quickly, we have to arrange it tabularly. Let's learn in this video that how to arrange the data...

Question

The data on modes of transport used by the students to come to school are given below. Draw a pie chart for the data.

Mode of transport	Bus	Cycle	Walking	Scooter	Car
Percentage of students	$40 %$	$30 %$	$15 %$	$10 %$	$5 %$

Accepted Answer

Converting the percentage into component parts of $360 °$ , we have

The central angle of a component $= \frac{percentage value of the component}{100} \times 360 °$

Mode of transport Percentage of students Central angle

Bus $40 %$ $\frac{40}{100} \times 360 ° = 144 °$

Cycle $30 %$ $\frac{30}{100} \times 360 ° = 108 °$

Walking $15 %$ $\frac{15}{100} \times 360 ° = 54 °$

Scooter $10 %$ $\frac{10}{100} \times 360 ° = 36 °$

Car $5 %$ $\frac{5}{100} \times 360 ° = 18 °$

Total $100 %$ $360 °$

Steps for construction of the pie chart:
1) Calculate the central angle for each component using the above formula and tabulate it.
2) Draw a circle of convenient radius and mark one horizontal radius in it.
3) Draw radius making central angle of first component with horizontal radius. This sector represents the first component. From this radius, draw the next radius with the central angle of the second component and so on, until the completion of all components.
4) For identification of each sector, shade with different colours.
5) Label each sector
