#### Objectives

- Visualize the solid generated by revolving the region bounded between two function graphs and the vertical lines x = a and x = b about the x-axis
- Calculate the area of a cross section of a solid generated by rotating the region bounded between two function graphs and the vertical lines x = a and x = b about the x-axis
- Use the area of a cross section of a solid generated by rotating a region bounded by two function graphs about the x-axis to find the exact volume of the solid

#### Vocabulary

- revolve about the x-axis
- solid
- washer
