Section 7.2 Finding Volumes by Integration
Guide to Writing Mathematics

• To read: All
• Be sure to understand: The section Solids of revolution

E-mail Subject Line: Math 104 Your Name 10/1

Reading questions:

1. Let R be the rectangle formed by the x-axis, the y-axis, and the lines y=1 and x=3. What is the shape of the solid formed when R is rotated about the x-axis?
2. Let T be the triangle formed by the lines y=x, x=1 and the x-axis. What is the shape of the solid formed when T is rotated about the x-axis?

Reminders:
