7th grade math help? Easy 10 points!

suppose you want to show the data in a circle graph. find the measure of the central angle for 5th grade. round your answer to the nearest degree if necessary.
4th 45 students
5th 25 students
6th 60 students
7th 50 students
8th 60 students
9th 45 students
Please show your work:)

The total number of students is 285. The central angle for the number of students in the fifth grade, therefore, is 360X25/285, which is 32 degrees (actually, 31.58 degrees, but you wanted it rounded to the nearest degree).

Count of all students = 45+25+60+50+60+45 = 285
Measure of the central angle for one student = (360/285) degrees
Measure of the central angle for 5th grade = (360/285)*25 degrees
= 31.578 degrees
So,, Measure of the central angle for 5th grade approximately equals to 32 degrees

first, we get the totlal number
of students. hence
45+25+60+50+60+45=285

since 5th grade has 25 students,
so, we have the percentage of 5th grade

25/285=0.08771 or 8.77%

in a circle degree in measure is 360⁰

hence , 360x0.0877

ans. ---- 31.58⁰ or 31⁰34⁰32.16
