I'm asked in an exercise to calculate the center of mass for $V=\{{(x,y,z)|x^2+y^2\leq 2x\sin(z), 0\leq z\leq \pi}\}$, but I'm having trouble doing this "the normal way" - the integral(s) I get seems unsolvable (I've tried calculating the integral in two orders: $dxdydz$ and $dydxdz$, both ended up in something unsolvable).
(The density of the body is the same for every point)
Help would be appreciated :)!
