A survey about the student government program at school finds of 245 students:

Question

• 218 students like the program
• 27 students think the program is unnecessary

If a circle graph were made from this data, what would the measure of the central angle be for the group that likes the program?

Please list the steps on how to get the correct answer. I found out the percentage the amount of kids who like the program takes up, but I couldn't seem to figure out how to get the central angle.

Answer 1

360° ∙ 218 / 245 = 360° ∙ 0,88979596 = 320.3265456° = 320° 19´ 36´´
