Question

At State College last term, 69 of the students in a Physics course earned As, 97 earned Bs, 121 got Cs, 91 were issued Ds, and 54 failed the course. If this grade distribution was graphed on a pie chart, how many degrees would be used to indicate the A region?Round your answer to the nearest whole degree.

Answer 1

Answer:

$58$

Explanation:

Here, we want to get the degrees that the grade A section will take on the piechart

Firstly,we need to add up all the values so we can get the total number of students who took the course

Matematically, we have this as follows:

$69\text{ + 97 + 121 + 91 + 54 = 432}$

Now, we proceed to divide the number of students who had an A by the total calculated above and multiply by 360 degrees

We have this as:

$\frac{69}{432}\times\text{ 360 }=\text{ 57.5 = 58 }$
