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

The approximate area is
`164,664.74\ mi^(2)` or the exact area is
`52,441\pi\ mi^(2)`

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)`
