Converting Triple Integrals to Spherical Coordinates.

Question

X goes from 0 to 2

Y goes from 0 to sqrt(4-x^2)

Z goes from 0 to sqrt(4-x^2-y^2).

 

The function is zsqrt(4-x^2-y^2)dzdydx.

 

I know the conversion from rectangular to spherical and the jacobian. I don't know how to convert this specific rectangular function into spherical. I also don't know how to calculate the limits of integration in spherical for this question. Please help and thanks!
