Homework Statement
use a double integral to find the volume of the solid bounded by.
z=x^2+2y^2 and z=12-2x^2-y^2
I want to change variables using polar coordinates, I know its the top minus the bottom, and the intersection between the two is a circle radius 2.
The Attempt at a Solution
I want to make sure i have the correct set up
[itex]\int^{2\pi}_{0}[/itex] [itex]\int^{2}_{0}[/itex] (12-3r[itex]^{2}[/itex])rdrd[itex]\theta[/itex]
