Question

Ten out of 22 students surveyed prefer milk with their breakfast. Find the measure of the central angle to represent this data in a circle graph.

A. about 164°
B. about 101

°  
C. about 10 °  
D. about 22 °

Answer 1

A. about 164
10/22 = 5/11
5*360 = 1800/11 = about 164

Answer 2

Option A is correct that is about 164°

Explanation:

Given: Number of students survey = 22

Number of students prefer milk with their breakfast = 10

We need to find measure of the central angle to represent it in a circle graph.

We know that total measures of central angles in a circle graph = 360°

So, Measure of central angle representing number of student preferring milk with breakfast =
`(10)/(22)*360`

=
`(3600)/(22)`

=
`163.64\:`

≈
`164\:(approx.)`

Therefore, Option A is correct that is about 164°
