Volume Question (Can someone check my work?)

  1. Aug 27, 2005 #1
    I posted this in the Calculus section also, so I apologize for double-posting.

    "Find the volume of the solid that lies within the sphere [tex]x^2+y^2+z^2=4[/tex], above the x-y plane, and below the cone [tex]z=\sqrt{x^2+y^2}[/tex]."

    I set this up in polar coordinates as follows:


    and then solved it coming up with [tex]V=\frac{8\pi\sqrt{2}}{3}[/tex].

    Is this the correct way to set this up? Also, is there a way I could do this with one double integral rather than adding two of them together?

    Thanks for your help.

    It is correct, and I think that was the simplest way to solve.
