1. 1

Recognize and use volume in solving multistep problems

Example

Note: Figure not drawn to scale.

The figure above shows a right circular cylindrical wheel of cheese inches high from which a wedge weighing pound has been cut. All cuts are perpendicular to the base and radiate from points and , the centers of the circular top and bottom. What is the weight, in pounds, of the original uncut wheel?

2. 2
