1-3.

In this course, a “flag” is defined as a geometric region 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.

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 .

Calculate the volume of the rotated flag.

Use the eTool below to visualize the flag.
