Write an iterated triple integral in the order dzdydx for the volume of the region bounded below by the xy-plane and above by the paraboloid $z = x^2 + y^2$ and lying inside the cylinder $x^2 + y^2 = 4$?
how can I solve this problem I already have the final answer but I don't know how to solve it, the answer to this problem is $(V=8(π-1/3)$ I tried solving it with this:
$\int_{-2}^2\int_{-\sqrt{4-x^2}}^{\sqrt{4-x^2}}\int_0^{x^2+y^2}dzdydx = 8π$
but it didn't work
