Question

when asked to give their choice,40% of students of a class opted for basketball. what would.be the central qngel of the sector representing this information on a pie chart
I will mark as the brainliast mark ​

Answer 1

Step-by-step explanation:

Given percentage of students of a class opted for basket ball =40%

In a pie chart sum of total angles =360°

it is for 100%

angle for 100%=360°

angle for 1%=360/100

angle for 1%=3.6°

Now for 40%=40×3.6=144°

Angle represents for 40% in the pie chart is 144°

=>40% of students opted for basketball

=>sum of angles in a pie chart =360° or 2π

=>100% represents 360° angle

=>10% represents 36° angle

=>then 1% represents =360/100=3.6° angle

Now,we have to calculate for 40%

=>40% represents 40×3.6=$\bold{\red{144° }}$angle.

Therefore,144° be the central angle of the sector
