equation of a circle of sorts?

To find the bounds, I would set z=0 and then solve for x and then y. For example...y = sqrt(24-x^2).

Homework Statement Find the volume between 2 paraboloids. Homework Equations z = 4x^2+8y^2 z= 30-x^2-y^2 The Attempt at a Solution So I switched the variables to polar coordinates. z = 30-r^2 z=4r^2*sin^2(θ)+8r^2*cos^2(θ) Now I want to solve for r. However I get a very...
