Answer:

[tex]522.12\pi[/tex] inches²

Step-by-step explanation:

The formula for finding the area of a circle is:

[tex]A=\pi r^2[/tex]

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

[tex]A=22.85^2\pi[/tex]

Now you calculate:

[tex]A=522.12\pi \\[/tex] inches²
