Answer:
Part A: OC. 16π square inches
Part B: OC. 36π square inches
Step-by-step explanation:
<u>Part A:</u>
Given
Diameter of circular picture = d = 8 inches
We need to find the radius first to find the area
So,
Rdius = r = d/2 = 8/2 = 4 inches

Therefore, option C is the correct answer..
<u>Part B: </u>
As two inches frame is added around the picture, the diameter will become 8+4 =12 inches
The new radius will be:
r = 12/2 = 6
So,

Therefore, option C is correct ..
