A circular park has a diameter of 9 km. Monument A is located by entering the park from the northern most point and proceeding due south for 3 km. Starting at the monument A and going due west you would eventually reach the edge (circumference) of the park. At that point, if you go due south for 1.5 km, you would reach the monument B.

Determine the distance between monument A and monument B.

4.5 km
