Question

thd data for the mode of transport used by 720 students of a school are given below-Mode of transport is bus240 cycle160 van is 180 and scooter is 140. represent the above data by a pie chart

Answer 1

Answer:

Step-by-step explanation:

Total number of students = 720

Students who have mode of transport as bus = 240

Fraction of total students = $\frac{240}{720}=\frac{1}{3}$

Angle formed at the center on pie chart = $\frac{1}{3}\times 360$ = 120°

Students who prefer to come by van = 180

Fraction of total students = $\frac{180}{720}=\frac{1}{4}$

Angle formed by at the center on pie chart = $\frac{1}{4}\times 360$ = 90°

Students who come school by scooter = 140

Fraction of students of total students = $\frac{140}{720}=\frac{7}{36}$

Angle formed at the center of pie chart = $\frac{7}{36}\times 360 = 70$ degree

number of students who come school by cycle = 160

Fraction of total students = $\frac{160}{720}=\frac{2}{9}$

Angle formed at the center of the pie chart = $\frac{2}{9}\times 360$ = 80°

Now we can draw a pie chart representing this data.

A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion.

In a pie chart, the arc length of each slice (and consequently its central angle and area), is directly proportional to the quantity it represents.

In a pie chart, each sector represents a particular part of data  

and  the magnitude of the sector is directly proportional to the magnitude of the specific part of the data
