### Problem 8.3

Posted:

**Sun Jan 14, 2018 6:32 pm**Air in a bicycle pump is compressed by pushing in the

handle. If the inner diameter of the pump is 3.0 cm and the

pump is depressed 20. cm with a pressure of 2.00 atm, (a) how

much work is done in the compression?

What needs to be done in order to get the correct answer. I know that we need to use the work equation, but what do we need to convert?
