Thanks for the reply. To be honest I hadn't even really considered using Cartesian coordinates. We have been covering spherical and cylindrical coordinates so I figured that the problem was probably designed for one of those two coordinate systems. Cartesian looks easier for this problem. Heres...

Find the total mass that occupies a solid region D bounded by a sphere of radius 3 centered at the origin and z = 1 if the density of the function is (x, y, z) = 1/1+x^2+y^2+z^2 . I would like to be able to do this problem using spherical coordinates but I am unsure about how...
