1-3.

We will define a "flag" as a geometric area attached to a line segment (its "pole"). An example is shown at right.

Imagine rotating the flag about its pole and describe the resulting three-dimensional figure. Draw a picture of this figure on your paper. To help you visualize this, use the .

Pretend you are the pole that is

ft tall. Hold out your ( ft) arm

perpendicular to your body and spin around. Imagine the shape. The shape is a cylinder with height of

and radius of . Find the volume of the rotated flag.

Use the eTool below to visualize the flag.
