Use the formula pi times the radius squared to get the area.

The radius is nine because the diameter of the diagram is 18. (The radius is always half the diameter).

π
r^2

π
9^(2)

Answer:

B. 254.3

Explanation:

The formula for the area of a circle is:


A = \pi\cdot r^2

and r is half the diameter.


r = 18in / 2 = 9in\\~\\A = \pi \cdot (9in)^2 \approx 3.14 \cdot 81in^2 = 254.34in^2
