Washer Action!!! (1)

The following applet illustrates how a WASHER is formed. Interact with the applet for a few minutes. Then, answer the questions that follow.


Suppose the RADIUS of the OUTER CYLINDER measures 4 inches. Suppose the radius of the INNER CYLINDER measures 3 inches. Suppose the height of both cylinders measures 6 inches. What would the volume of the remaining WASHER be? Show your reasoning & thought process!


Explain, in words, what you mathematically need to do to find the volume of any washer that looks like any of the ones you can form in the applet above.
