15. 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 thinks the program is unnecessary?
98º******
27º
90º
172º
Is my math right?
110+120+210=440 120/440=.27
.27*360=98
Actually, and im not sure how this is supposed to be solved, but the answer is 172.
172 is the right
It’s D
Math is crazy, lets leave it at that.
Yeah! Its D tanks!
ok sooo 172 right
For the ones who have it as "the group that likes the program" it would be
110 (students who like) / 440 (Total amount) = 25*
There are different variations of this test If you didn't notice from all the Reponses
Sure, let's solve it step-by-step:
First, we find the total number of students who participated in the survey:
Total number of students = students who like the program + students who think the program is unnecessary + students who plan on running for student government next year
Total number of students = 110 + 120 + 210 = 440
Now, we find the percentage of students who like the program:
Percentage of students who like the program = (Number of students who like the program / Total number of students who participated in the survey) x 100
Percentage of students who like the program = (110 / 440) x 100 = 25%
Finally, we find the measure of the central angle for the group that likes the program:
Measure of central angle = 25% x 360° = 90°
Therefore, the central angle for the group that likes the program is 90 degrees.
Can some show how to solve it with the numbers 190,135,220 please
Actually my idea's wrong. My bad
Bot I need help?
Sure, what do you need help with?

@Nausica, you are almost right but i'm pretty sure it's not 120/440, it's 440-120. That's my only explanation to get D.
You are all wrong its 90%
IT WASN'T 172!
It was 98...
Total number of students is 440 (110+120+210)
set up a ratio
120/440=m/360
cross multiply
120 x 360 = 440m
43,200=440m
43,200/440=m
98.181818=m
The answer is 98 degrees
