If you plug that into a calculator you get 4.5
A=1/2bh + A=lw A=1/25x12 A=30 + A=9x8 A=72 72+30=102
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 = <span>254.34
</span>
Then multiply 2 to get the double the area.
254.34 * 2 = <span>508.68
</span>
So, the answer to this question is <span>D. 508.68 in. 2.</span>
