A horizontal flag, composed of a quarter-circle and a rectangle, is shown at right. Homework Help ✎

  1. Imagine rotating the flag about its 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.

  2. Calculate the volume of the rotated flag.

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