Question

A torus is formed when a circle of radius2 centered at [3, 0] is revolved about the yaxis. Use the shell method to write an integral for the volumeof the torus.

Answer 1

y² + (x - 3)² = 4 is the equation.

Explanation:

The equation of the said circle is

y² + (x - 3)² = 4

y = √[4 - (x - 3)²]
