i just need to know if i got the right answer. plz thankyou
a 15000N car on a hydrolyic lift rests on a cylinder with a piston of radius 0.20M,. if a connecting cylinder with a piston of 0.04M radius is driven by compressed air, what force must be applied to the smaller piston in order to lift the car?

am i doing this right?
pi*(0.04M)^2 / pi(0.20M)^2* 15000N = 600N
is this right, if not how do i go about getting the right anwser?

    Yes, correct. Pressure (force/area) is the same on each piston.
