Thank you and Merry Christmas for you too!

I've also tried to calculate it integrating z in that way \int \int( \int^{\sqrt{9-x^2-y^2}}_{\sqrt{x^2+y^2}} (xy+z) dz)dxdy and then changing to polar coordinates with x and y What do you think about it?

Well, I'm not sure, the solid bounded by those surfaces it's inside the sphere but outside the cone, so i thought beta angle goes from the straight lines that form cone, to the plane z=0, considering that beta angle starts at the z-axis

Homework Statement Well, first of all, I'm not english spoken, so sorry for the mistakes. I was trying to calculate the integral below: \int \int \int_{V} (xy+z) dxdydz where V is a region in R^{3} bounded by the sphere x^2+y^2+z^2<=9 the cone z^2<=x^2+y^2 and the plane...
