The following applet illustrates how a

**WASHER**is formed. Interact with the applet for a few minutes. Then, answer the questions that follow.## 1.

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!

## 2.

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.
