Question

Erica surveyed students at her school about their favorite type of music. She made a circle graph to show the results. The central angle for the section of the graph that represents country music measures 72°. If 45 classmates chose country as their favorite type of music, how many students did Erica survey?

Answer 1

Explanation:

So if 72 = 45 then 360 = x

so 360x 45/72 which is 225
