What circular area is covered by the signal if the

circumference is 754 miles?

A = 45216 miles^2

Step-by-step explanation:

We can find the radius

C = 2 * pi * r

754 = 2 * pi * r

Divide each side by 2 pi

754 / 2pi = 2 * pi * r / 2 pi

377/pi = r

Approximating 3.14 for pi and rounding the radius to the nearest mile

120 = r

Now we need to find the area

A = pi r^2

A = 3.14 (120) ^2

A = 3.14 (14400)

A = 45216 miles^2
