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
~I believe it would be about 35%
I just wanna know how to do it

To find the measure of the central angle for the group that likes the program, we need to calculate the percentage of students in that group.
The total number of students is 190 + 135 + 220 = 545.
To find the percentage of students who like the program, divide the number of students who like the program by the total number of students and multiply by 100:
(190 / 545) * 100 = 34.8623
Rounding to the nearest whole number, the measure of the central angle for the group that likes the program is 35%.
To find the measure of the central angle for the group that likes the program, we need to determine the percentage of students who like the program out of the total number of students.
First, we need to find the total number of students. This can be calculated by adding the number of students who like the program and the number of students who think the program is unnecessary. So, the total number of students is 190 + 135 = 325.
Next, we can calculate the percentage of students who like the program by dividing the number of students who like the program by the total number of students and then multiplying by 100.
Percentage of students who like the program = (190 / 325) * 100 ≈ 58.46%
Now, let's calculate the measure of the central angle by multiplying the percentage by 360 (since there are 360 degrees in a circle).
Measure of the central angle = 58.46% * 360 ≈ 208.84
Rounding to the nearest whole number, the measure of the central angle for the group that likes the program is approximately 209 degrees.
