For the integral $$\int_{-1}^{0} \int_{-\sqrt{4-x^2}}^{0} 1 x y\,dy\,dx,$$ sketch the region of integration and evaluate the integral.

Your sketch should be approximately the same as one of the graphs shown below; which is the correct region? Graph ? 1 2 3 4 5 6

Then $\int_{-1}^{0} \int_{-\sqrt{4-x^2}}^{0} 1 x y\,dy\,dx =$
