Please help I keep getting the wrong answer :/

In a car lift used in a service station, com-
pressed air exerts a force on a small piston
of circular cross-section having a radius of
4.83 cm. This pressure is transmitted by a
liquid to a second piston of radius 20.3 cm.
What force must the compressed air exert
in order to lift a car weighing 11700 N?
Answer in units of N

aww thanks for the suggestion @PhysicsGuru but that was incorrect.

Ok the equation for pressure is P = F/A

So the top pressure of the 2nd piston is P = 11700 N / pi(0.203m)^2

The pressure on the 1st piston must be the same so

11700 N / pi(0.203m)^2 = Fair / pi(0.0483m)^2

Solve for Fair

Thank you! I wasn't dividing by pi
