Question

Mr. Allway’s math class surveyed all the seventh-grade students to find out their favorite sport.The following circle graph shows a breakdown of the survey findings.A circle graph with 39% football, 28% baseball, 30% basketball, and 3% otheranswer choices:101°108°140°11°

Answer 1

A pie chart or circle graph divides the area of a circle into percentages representing each section. The entire area is equal to 360 degrees.

So, if the basketball section comprises 30% of the circle, then it is equal to 30% of 360 degrees. In equation form, we write this as:

`\begin{gathered} 30\%*360\degree \\ =0.30*360\degree \\ =108\degree \end{gathered}`

So the answer is 108 degrees.
