Here's another kind of pressure problem. A force of 22 pounds presses on a membrane. The average pressure on the membrane is 2.75 pounds per square inch (psi). What is the area of the membrane in square inches? The equation for calculating pressure is P = F/A where P is pressure. F is force, and A is area.
F = 22 lb.
A = ? sq. in.
