This problem is similar to this however, in my case my cylinder is not at (0,0).
Use double integrals to determine the volume of the solid bounded by:
$$x^2+y^2\leq2y \qquad z\leq2-x^2-y^2 \qquad z=0$$
When $z=0$ we have the following plot
$$(\sqrt2)^2=x^2+y^2 \qquad x^2+(y-1)^2=1$$
Thus, the integration region is defined by the intersection. Which method should I use to integrate?

In cylindrical coordinates the bounds are given by \begin{align} 0\le\ &z\ \le 2-r^2 \\ 2\cos(\theta)\le\ &r\ \le \sqrt{2} \\ -\pi/4 \le \ &\theta\ \le \pi/4 \end{align} The volume of the region is just the triple integral $$\int_{-\pi/4}^{\pi/4}\int_{2\cos(\theta)}^{\sqrt{2}}\int_{0}^{2-r^2}r\ dzdrd\theta$$ I will leave the computation to you.
