Question

what will be the angle measures for the students who use
the following means of transport to come to school?
Transport :
walk , Bus , cycle , car.
No. of students [ 30,25,20,15 ]​

Answer 1

In a pie chart the whole angle=360°

Total student = 30+25+20+15=90

Now, angle for walk=(30/90)×360

=120°

. angle for bus=(25/90)×360=100°

. Angle fir cycle=(20/90)×360=80°

. angle for car=(15/90)×360=60°
