Question

A ratio station is allowed by the FFC to broadcast over an area with a radius of 219mi. how much area is this?

Answer 1

Answer:

The approximate area is $164,664.74\ mi^{2}$ or the exact area is $52,441\pi\ mi^{2}$

Step-by-step explanation:

we know that

The area of a circle is equal to

$A=\pi r^{2}$

we have

$r=229\ mi$

substitute

$A=\pi (229^{2})=52,441\pi\ mi^{2}$

assume $\pi=3.14$

$52,441(3.14)=164,664.74\ mi^{2}$
