What is the volume of the solid generated by revolving the region enclosed by (x-2)^2 + y^2 = 1 about the y-axis?
Hello, chaddy!
What is the volume of the solid generated by revolving the region
enclosed by about the y-axis?
Make a sketch. We have a circle with center (2,0) and radius 1
. . revolved about the y-axis.
This results in a torus (donut).
I recommend using Shells: .
The radius is:
The height is: .
We must evaluate: .
Good luck!
