I need the steps explained on how to do this here ill type the whole question

Answer 5

A survey about the student government program at a school finds the following results.
190 students like the program
135 students think the program is unnecessary
220 students plan on running for student government next year.

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? Round your answer to the nearest whole number.

Answer 6

the size of the angle depends on how big the group is, compared to the other groups

the 190/(190+135+220) part means that we are calculating the fraction of people who like the program

Answer 7

people who like the program/total people = 190/(190+135+220)

with me so far?

Answer 8

Yes

Answer 9

good, now we need to figure out how we would put this on a pie graph

Answer 10

a pie graph is a circle, so the whole thing is 360 degrees

so we take our fraction from before:

190/(190+135+220)

and multiply that by 360 to figure out how big the section needs to be

Answer 11

okay

Answer 12

it says to round to the nearest whole number, so your final answer would be 126 degrees

Answer 13

Thank you so much
