a. 2,034.72 in.2
b. 113.04 in.2
c. 254.34 in.2
d. 508.68 in.2

D

Step-by-step explanation:

First, the area of the pizza then double it.

Area for a circle: Area = * r^2

Plug in the values.

We will use 3.14 for .

We need the radius. So half the diameter to get the radius.

18 / 2 = 9

Area = 3.14 * 9^2

Area = 3.14 * 81

Area = 254.34

Then multiply 2 to get the double the area.

254.34 * 2 = 508.68

So, the answer to this question is D. 508.68 in. 2.
