A low-wattage radio station can be heard only within a certain distance from the station. On the graph below, the circular region represents that part of the city where the station can be heard, and the center of the circle represents the location of the station. Find the standard equation of the circle.
Answers:
A: (x+3)^2 + (y-2)^2 = 9
B: (x-3)^2 + (y+2)^2 = 9
C: (x+3)^2 + (y-2)^2 = 18
D: (x-3)^2 + (y+2)^2 = 18
