A survey about the art program at a school found that 250 students wanted an afterschool art program, 150 students wanted art classes during the day, and 100 students thought that the school should have no art program. If a circle graph were made from this data, what would be the measure of the central angle for the “afterschool” group?

Find the fraction part first, which would be 0.5 then multiply by 360. 0.5 x 360= 180

250 out of 500 students is going to give you 0.5. After that you will need to multiply that number by 360. your equation will look something like this: 0.5 x 360 = 180
your welcome! :)
