The radar system in an airport determines the location of inbound and outbound planes once they are within range. The range, based on the signal from the tower, is represented by the polar equation r = 10cos(θ). Which graph represents the signal range of the airport’s radar system?
Answer
A

B
On a polar coordinate plane, a circle goes through (0, 0) and (10, StartFraction 3 pi Over 2 EndFraction).
C
On a polar coordinate plane, a circle goes through (0, 0) and (10, pi).
D
On a polar coordinate plane, a circle goes through (0, 0) and (10, StartFraction pi Over 2 EndFraction).
