Answer:

C, 1 : 16

Step-by-step explanation:

Small Circle

The radius is half of the diameter. 3 inches.

π×r²=A

We'll use 3.14 for pi.

3.14×9

28.26 in²

Bigger Circle

6×4= 24

So the diameter is 24. The radius is 12.

3.14×12²

3.14×144

452.16 in²

Let's divide.

452.16÷ 28.26

= 16

Therefore, the answer is C, 1 : 16.

Hope this helps, please mark brainliest if possible :)

Area of the sector = 1/2 * r^2 * theta where theta is the angle subtended by the arc at the center  ( in radians)

In this case m < theta = 360 - 235 = 125 degrees or  2.182 radians

So, the area of shaded area = 1/2 * 20^2 * 2.182 =   436.4 in^2
