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°

Option A is correct that is about 164°

Step-by-step 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 =

                               =  

                               =  

                               ≈  

Therefore, Option A is correct that is about 164°
