Homework Statement
Bounded by the paraboloid z = 4 + 2x2 + 2y2 and the plane z = 10 in the first octant.
Homework Equations
The Attempt at a Solution
Plugging in 10 for z I got 3=x2+y2. From this, I set 0[tex]\leqr[/tex][tex]\leq3\sqrt{}[/tex].
I wasn't sure what to do with the first octant, but I guess that it meant 0[tex]\leq\vartheta[/tex][tex]\leq/2\pi[/tex]
I set my equation to be -6+2r2r dr d[tex]\vartheta[/tex].
After integrating I got -9[tex]\pi[/tex]/4
This was wrong. Any idea where I messed up? Thanks
