Question 2

mylen [45]

Answer:

Part A: OC. 16π square inches

Part B: OC. 36π square inches

Step-by-step explanation:

Part A:

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

$Area = \pi r^2\\= \pi *(4)^2\\= 16\pi\ square\ inches$

Therefore, option C is the correct answer..

Part B:

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,

$Area\ with\ frame = \pi r^2\\=\pi *(6)^2\\=36\pi\ square inches$

Therefore, option C is correct ..
