Question

The frequency table above is presented as a pie chart

The sectorial angle of score"3" is ....
​

Answer 1

`Angle = 96`

Explanation:

Given

The frequency table

Required:

Determine the sectorial angle of "3"

First we need to determine the total frequency;

`Total = 3 + 4 + 6 +8 + 5 + 4`

`Total = 30`

The sectorial angle is calculated as thus;

`Angle = (Frequency)/(Total\ Frequency) * 360`

Where Frequency of "3" = 8

So;

`Angle = (8)/(30) * 360`

`Angle = (8* 360)/(30)`

`Angle = (2880)/(30)`

`Angle = 96`

Hence; the sectorial angle of "3" is 96
