Answer:
AB = 8r * Sqrt(2)
PA = 4r * Sqrt(2)
Step-by-step explanation:
Triangle PAC is similar to triangle PBD. So:
PA/PB = PC/PD = AC/BD = 2r/6r = 1/3
PC/PD = 1/3
=> PD = 3PC
=> CD = 2PC
=> PC = CD/2= 12r/2 = 6r
PA^2 = PC^2 - AC^2 = (6r)^2 - (2r)^2 = 32r^2
=> PA = Sqrt(32) * r = 4r * Sqrt(2)
AB = 2*AP (because PB = 3PA) = 8r * Sqrt(2)
