Homework Statement
The top of a rubber band bushing is designed to absorb vibrations in an automobile is the surface of a revolution generated by revolving the curve z = (0.5y^2) + 2
for (0<= y <= 3) in the yz plane about the z axis.
use the shell method to find its volume.
Homework Equations
V = 2pi ∫radius*height dy
The Attempt at a Solution
v = 2pi ∫y(4-0.5y^2) dy evaluated from 0 to 3.
This is wrong, how to i go about setting up the integral for this? Have trouble with these.
