Question

Find the area of the figure to the nearest tenth.

Answer 1

A. 99.0 in^2
B. 31.5 in^2
C. 11.0 in^2
D. 155.5 in^2

Answer 2

The area of the entire circle is
PI * r^2

3.14159 * 9*9 = 254.47

You want to find the area of 140 degrees out of 360 degrees
so you would multiply 254.47 * (140/360)
= 98.96
So your answer is A

Answer 3

\[\frac{140 \pi 9^2}{360}=98.9602 \]
