The following applet illustrates how a [b]WASHER [/b]is formed. [br][br]Interact with the applet for a few minutes.[br]Then, answer the questions that follow.
Suppose the RADIUS of the [b][color=#bf9000]OUTER CYLINDER[/color][/b] measures 4 inches. [br]Suppose the radius of the [color=#ff00ff][b]INNER CYLINDER[/b][/color] measures 3 inches. [br]Suppose the [b][color=#666666]height[/color][/b] of both cylinders measures 6 inches. [br][br][b]What would the volume of the remaining WASHER be? [/b] Show your reasoning & thought process!
V = 42*pi cubic inches, or approximately 132 cubic inches.
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.
