My current object with this problem is just to get to the integral. Once I have that I can solve for volume myself.
The Question is:
Here's a graph of the function as well:Quote:
The volume of the solid obtained by rotating the region enclosed by
about the y-axis can be computed using the method of disks or washers via an integral
with limits of integration and
The volume is
I use the flowing formula:
This is what I think the integral should be, but it's not.
