A. 24 miles
Explanation:
the area inside a circle is given by:
[tex]A=\pi r^2[/tex]
where r is the radius of the circle.
In this problem, we know the circular area:
[tex]A=1,808.64 mi^2[/tex]
So we can re-arrange the equation above to find r, the radius:
[tex]r=\sqrt{\frac{A}{\pi}}=\sqrt{\frac{1,808.64}{\pi}}=24.0 mi[/tex]
so, the radius of the circular area is 24 miles.
