Determine the area of the circular region that can be reached by the radio station signal using the equation.
                               A = πD²/4
A is area and D is diameter. Using 3.14 as pi value. 
                             A = (3.14)(120 mi)² / 4 
                             A = 11304 mi²
Knowing that in each of the squared miles, 100 people live.
  total population receiving the signal = 11304 mi² x (100 people / 1 mi²)
                                    = 1,130,400
Thus, the answer is letter C.
