Question

A survey about the student government found that 350 students wanted after-school student government programs, 210 students wanted student government classes during the day, and 140 students thought that school should have no student government program.
If a circle Graph were made from this data, what would be the measure of the central angle for the "in school" group?

Answer 1

the "in school" group is the 210 or 140?

Answer 2

or 350?

Answer 3

I'm not quite sure, but I don't think it's the 140. Maybe it's talking about the overall students that want the student government program?

Answer 4

uhh then would that be 360? because the overall student is the whole circle so whole circle has angle 360....?

Answer 5

or maybe "in school" is just the opposite of the "after school" so the "in school" group would be 210...

Answer 6

right?

Answer 7

I guess...I really have no idea! But that makes more sense(:

Answer 8

now...can you figure out the *total* number of students?

Answer 9

700 students total

Answer 10

good. now then...the fracttion of the "in school" group would be 210/700
agree?

Answer 11

agreed...So this would be worked out like a ratio, right?

Answer 12

i believe so

Answer 13

can you *simplify* that fraction now?

Answer 14

3/10

Answer 15

good. now multiply it to 360

Answer 16

108

Answer 17

right. so there's your angle

Answer 18

Well that was much simpler than I thought(: Thanks lgba!
