Step 1:

The equations are $\"\"$ and $\"\"$ .

The volume of the solid generated revolving about the line $\"\"$ .

Washer method:

$\"\"$

Where $\"\"$ is outer radius and $\"\"$ is inner radius.

The outer radius of revolution is $\"\"$ .

The inner radius of revolution is $\"\"$ .

Substitute $\"\"$ , $\"\"$ in $\"\"$ .

$\"\"$ .

Integrate between 0 and 3.

$\"\"$

Apply formula $\"\"$ .

Apply power rule $\"\"$ . \ \

$\"\"$

The volume of solid is $\"\"$ cubic units.

Solution:

The volume of solid is $\"\"$ cubic units.
