Answer:

\large\boxed{A=144\pi\ in^2\approx452.16\ in^2}

Step-by-step explanation:

A diameter is two times longer than a radius. Therefore, if the diameter

d = 24in, then the radius r = (24in) : 2 = 12in.

The formula of an area of a circle:

A=\pi r^2

Substitute:

A=\pi(12)^2=144\pi\ in^2

\pi\approx3.14

Then

A\approx(144)(3.14)=452.16\ in^2
