Distance of A from cliff = 1500·arctan(30°) ≅ 723.5 ft 
distance of B from cliff = 723.5+1000√3 ≅ 2455.6 ft 
tanθ = 2455.6/1500 = 1.637 
θ = arctan(1.637) ≅ 58.6° 
angle of depression = 90-θ ≅ 30°
        
             
        
        
        
The answer should be d
64pi=4pir^2
cancel the pi
64=4r^2
16=r^2
r=4
