Answer:

The approximate area is [tex]164,664.74\ mi^{2}[/tex] or the exact area is [tex]52,441\pi\ mi^{2}[/tex]

Step-by-step explanation:

we know that

The area of a circle is equal to

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

we have

[tex]r=229\ mi[/tex]

substitute

[tex]A=\pi (229^{2})=52,441\pi\ mi^{2}[/tex]

assume [tex]\pi=3.14[/tex]

[tex]52,441(3.14)=164,664.74\ mi^{2}[/tex]
