Question

The data on modes of transport used by students to come to school are given . Represent the data with the help of a pie chart.

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

Answer 1

Hint:
First find out the angle that subtends on the centre of the pie chart its formula is equal to \[\dfrac{{{\text{Percentage of students }} \times {\text{ 360}}^\circ }}{{100}}\] after finding the angle of each mode of transport draw the pie chart .

Complete step by step solution:
In this question we have to make the pie chart of the given data on modes of transport used by students to come to school .
So for making the pie chart first we have to divide the angle of circle , as we know that the whole circle make $360^\circ $ at the centre of it , so we have to divide $360^\circ $ according to the percentage of students
As from the given we have know that the percentage of students
So the given mode of transport sustain angle at centre is equal to
 = \[\dfrac{{{\text{Percentage of students }} \times {\text{ 360}}^\circ }}{{100}}\]
For mode of transport of Bus is $40\% $
Angle at centre is equal to $\dfrac{{40 \times 360}}{{100}}$ = $144^\circ $
For mode of transport of cycle is $30\% $
Angle at centre is equal to $\dfrac{{30 \times 360}}{{100}}$ = $108^\circ $
For mode of scooter of Bus is $10\% $
Angle at centre is equal to $\dfrac{{10 \times 360}}{{100}}$ = $36^\circ $
For mode of transport of car is $5\% $
Angle at centre is equal to $\dfrac{{5 \times 360}}{{100}}$ = $18^\circ $
For mode of transport of walking is $15\% $
Angle at centre is equal to $\dfrac{{15 \times 360}}{{100}}$ = $54^\circ $
Hence make pie chart and divide the angle subtends at the centre of circle as following

Mode of transport	Bus	Cycle	Scooter	Car	Walking
Percentage of students	$40\% $	$30\% $	$10\% $	$5\% $	$15\% $
Angle subtended at centre of pie chart	$144^\circ $	$108^\circ $	$36^\circ $	$18^\circ $	$54^\circ $

It is a required pie chart .

Note:
There are many types of chart for example pie chart , Bar chart ,Line chart , Area chart etc
For comparing the frequencies of the given data we will use the Bar Charts for example if we have to compare that Runs scored by a batsmen in the following years so we make the bar chart of the Batsman runs vs. year from here we will compare easily .
A line chart is a graphical representation of an asset's historical price action that connects a series of data points with a continuous line
