Question

Find the area of the shaded region to the nearest tenth.​

Answer 1

50 in

Explanation:

(1)

`area \: of \: the \: whole \: circle \: = \pi {r}^(2)`

= 22 × 5 ×5

7

= 78.57

(2)

`area \: of \: the \: unshaded \: circle \: = \pi {r}^(2)`

= 22 × 3 ×3

7

= 28.28

(1) - (2) = Area of shaded circle

= 78.57 - 28.28

= 50.29
