In a car lift, compressed air exerts a force on a piston with a radius of 3.18 cm. This pressure is transmitted to a second piston with a radius of 13.0 cm.
a) How large a force must the compressed air exert to lift a 1.32 x 104 N car?
b) What pressure produces this force? Neglect the weight of the pistons.
