algebra

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 the data, what is the measure of the central angle for the group that likes the program.

I'm not sure what I have to do first? I could probably figure it out if I know the steps on how to solve it.

  2. Do you multiply .25 x 440 to get the answer? (25 degrees)

  3. what on earth do the students who run for government have to do with this? Leave them out, part of another survey.
    We asked 230 students about this program evidently
    110 of them liked it
    so
    (110/230)(360 degrees) = 172 degrees

  4. If you did include them all (I wonder how many government candidates liked the program?)
    then
    .25 * 360 = 90 degrees
