Answer:
Explanation:
Calculate the number of square miles if d = 120 miles
d = 120 miles
r = d/2
r = 120/2 miles
r = 60 miles
Area of radio station coverage. = pi * r * r
Area of radio station coverage = 3.14 * 60 * 60 = 11304 square miles.
1 square mile contains 100 people
11304 square miles contain x people
Set up a proportion
1 / 11304 = 100 / x Cross multiply
x = 100 * 11304 Combine
x = 11304 * 100
x = 1130400
That's the answer. You have to choose the correct reply.
