5-11.

A horizontal flag, composed of a quarter-circle and straight line segments, is shown below.

Imagine rotating the flag about its horizontal pole and describe the resulting three-dimensional figure. Draw a picture of this figure on your paper.

If the flag were rotated it would look like a mushroom.

Find the volume of the rotated flag.

Use geometry to find the volume of the resulting three-dimensional figure.
