Math Help - Double integration problem.

1. Double integration problem.

$\int_{x = 0}^2 {\int_{y = 0}^{\sqrt {4 + {x^2}} } {y\sqrt {{x^2} + {y^2}} } } dxdy$

I tried using integration by substitution but couldn't get an answer. Any help would be appreciated. Thanks

2. Did you try using polar coordinates?
