The radius of the circle is r = 8.
The formula for the area of circle is,
[tex]A=\pi\cdot(r)^2[/tex]Substitute the value of r in the formula to determine the area of circle.
[tex]\begin{gathered} A=\pi\cdot(8)^2 \\ =201.061 \\ \approx201.1 \end{gathered}[/tex]So area of circle is 201.1 miles square.
