Homework Statement
The surface of a double lobed cam are modeled by the inequalities:
[itex]\frac{1}{4}[/itex][itex]\leq[/itex]r[itex]\leq[/itex][itex]\frac{1}{2}[/itex](1+cos2θ)
and
-9/(4(x2+y2+9)) ≤ z ≤ 9/(4(x2+y2+9))
Find the volume of the steel in the cam.
Homework Equations
The Attempt at a Solution
I know I need to use a double or triple integral to solve this. I was thinking since I was given r I could change to polar coordinates and solve that way.
Please give me some guidance.
