To change to cylindrical coordinates from rectangular coordinates use the conversion:

To change to spherical coordinates from rectangular coordinates use the conversion:

Using a triple integral to find the volume of a solid translates in the following manner:

- Given the rectangular equation for a circular cone:

**A)**- Graph the equation using the domain values of , and the range values .
**B)**- Find the equation of the cone in cylindrical coordinates and then graph the equation. Write the equation in text in its simplest form.
**C)**- Find the equation of the cone in spherical coordinates and graph it. Write the equation of the equation in text in its simplest form.

- Use rectangular coordinates and a triple integral to find the volume of a right circular cone of height . Now repeat this using cylindrical coordinates. Which method is easier?
- Now suppose an ice cream cone is bounded below by the same equation of the cone given in exercise 1 and bounded above by the sphere . Find the volume of the ice cream cone using a triple integral in spherical coordinates. Include a plot of the ice cream cone.
