Find the area of the sector by multiplying the area of the circle by the ratio of 360.

length of radius
length of diameter
measure of central angle
measure of circle

C. Measure of central angle.

Step-by-step explanation:

We have been given a statement about of a circle. We are asked to choose the correct option that will complete our given statement.

We will use area of sector to solve our given problem.

, where,

= Measure of central angle,

= Area of circle.

We know that area of sector can be found by multiplying the area of circle by the ratio of the measure of central angle to 360.

Therefore, option C is the correct choice.
