Question

For

Part B
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= where Pis pressure, Fis force, and A is area.
F= 22 lb.
ents
A = ? sq.in.

Answer 1

Let's see

• P=F/A
• 2.75=22/A
• A=22/2.75
• A=8in²

Answer 2

8 in^2.

Explanation:

F = P * A

22 = 2.75 * A

A = 22/ 2.75

A = 8 in^2.
