I hope I'm reading this right but the circle has a radius of 9?

a = π r²

81π or 254.34

The equation for the area of a circle is: $\pi r^2$ . Insert 9 as your radius (r) into the equation and solve:
\pi 9^2 = 254.469

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:

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

FM radio station

Given:

r = 40 miles

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

AM radio station

Given:

r = 4 miles

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

Difference:

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