Answer:

$2268\pi\ or\ 7,121.52$

Step-by-step explanation:

$A = \pi (\frac{D}{2})^2 = \pi (\frac{18}{2})^2 = \pi 9^2 = 81\pi$

$V = A * h = 81\pi * 28 = 2268 \pi = 7,121.52$

An FM radio station signal travels in a 40-mile radius. An AM radio station

MrMuchimi

Answer:

4976.28 square miles (nearest hundredth)

Step-by-step explanation:

$\textsf{Area of a circle}=\pi r^2 \quad \textsf{(where r is the radius)}$

<u>FM radio station</u>

Given:

r = 40 miles

$\implies \textsf{Area}=\pi (40)^2=1600 \pi \: \sf miles^2$

<u>AM radio station</u>

Given:

r = 4 miles

$\implies \textsf{Area}=\pi (4)^2=16 \pi \: \sf miles^2$

Difference:

$\begin{aligned}\implies \textsf{FM area - AM area} & =1600 \pi - 16 \pi\\ &= 1584 \pi\\ & =4976.23\:\textsf{square miles (nearest hundredth)}\end{aligned}$
