Answer:


522.12\pi inches²

Explanation:

The formula for finding the area of a circle is:


A=\pi r^2

If you put 45.7/2 (because you have the diameter and NOT the radius) instead of r you get:


A=22.85^2\pi

Now you calculate:


A=522.12\pi \\ inches²

Answer:

half of 45.7 is 22.85

22.85^2 = 522.1225
