To find the volume of the solid of revolution formed by revolving the region bounded by
and the
-axis over the interval
about the line
, we can use the washer method.
First, we determine the outer radius
and the inner radius
:
- The upper curve is
. - The distance from
to (outer radius) is given by: - The distance from
to the -axis (inner radius) is:
Next, we set up the volume integral:
Calculating the squares:
Now substitute back into the volume integral:
Integrating term by term:
Calculating at the bounds:
- Upper bound at
:
- Lower bound at
:
Now subtract:
So, the volume of the solid of revolution is:
