Physics: Find ratio of large force to the small force?

In a hydraulic lift the radii of the pistons are 1.75 cm and 14.0 cm. An SUV of mass 1850 kg is to be ifted by the force of the large piston. (a) Find the mechanical advantage of the lift (ratio of the large force to the small force).(b) What force must be applied to the small piston to lift the SUV? (c) When the small piston is pushed 10.0 m, how far is the car lifted?Thank you!
