Question
#10 At State College last term, 59 of the students in a Physics course earned an A, 84 earned a B, 123 got a C, 84 were issued a D, and 62 failed the course. If this grade distribution was graphed on pie chart, how many degrees would be used to indicate the C region?

1. Calculate the total number of students:
59 + 84 + 123 + 84 + 62 = 412
2. Use the formula to find the degree measurement for students who got a C:
\frac{123}{412}\times360\approx107.47^{\circ}
3. The degree measurement for the C region in the pie chart is:
\approx107.47^{\circ}
2. Use the formula to find the degree measurement for students who got a C:
3. The degree measurement for the C region in the pie chart is:
