A survey about the student government program at a school finds the following results:
110 students like the program.
120 students think the program is unnecessary.
210 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?
25 degrees
90 degrees
98 degrees
172 degrees

172 degrees

Using this equation, find x:
Children who like it/total children=measure of angle/total degrees in circle
110/440=x/360

This should give you what you are looking for. I took geometry last year and, correct me if I'm wrong but, a central angle has the same degree as the arc it creates so find x and that should be your answer.

So 25% @alexishope47  thanks so much!

How did you solve for x?

alexishope47 · Answer

I got a different answer.

tanabugg · Answer

I did 110/ 440= 0.25.

alexishope47 · Answer

Try solving by cross multiplying. Like they are fractions.

110/440=x/360
(360)*(110)=440x

That's how I always did it in school.
