First, the area of the pizza then double it.
Area for a circle: Area = [tex] \pi [/tex] * r^2
Plug in the values.
We will use 3.14 for [tex] \pi [/tex].
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.

Answer: 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
