Answer:

[tex]Area = 615.44 miles[/tex] is the circles area.

Explanation:

Before we answer the math problem, let's examine what we know so far.

[tex]\left[\begin{array}{cc}raidus =14miles\\Diameter = 28miles\\circumference = 87.92 miles\end{array}\right][/tex]

In Terms of Pi π

circumference = 28 π mi

Area = 196  mi^2

[tex]Diameter - Steps[/tex] - How I found the diameter ( R stands for Radius )

[tex]d = 2r\\d = 2 *14\\d = 28[/tex]

[tex]circumference - Steps[/tex] - How I found the circumference

[tex]C = 2\pi r\\C= 2 *\pi *14 \\C= 28\pi \\C = 87.92[/tex]

[tex]Area-Calcuating[/tex] ( The circules area )

[tex]A =\pi r^2\\A=\pi *14^2\\A =196\pi \\A=6.15.44miles[/tex]

So, [tex]Area = 615.44 miles[/tex] is the circles area.

Hope this helps! :D
