Pre-Algebra

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.

If someone could please help me fore I do not understand what it wants me to do.

  1. 360° is the whole circle.
    You have 190 out of a total of 545 students who like the program.

    So, you want 190/545 = 0.3486 or 34.86% of the whole circle
    That is, 0.3486 * 360 = 125.5°
