Homework Help: Simple pressure problem

  1. Nov 29, 2016 #1
    1. The problem statement, all variables and given/known data

    Find the pressure increase in the fluid in a syringe when a nurse applies a force of 43 N to the syringe's circular piston, which has a radius of 1.1 cm.

    2. Relevant equations


    3. The attempt at a solution
    So the answer should just be the force multiplied by the area of the plunger, no?
    43N*pi*0.011m^2
    0.016346 Pa

    No. How is the pressure defined?
