I am suppose to evaluate this integral in spherical coordinates

f(x,y,z) = 1/ (x^2 + y^2 + z^2)^(1/2) over the bottom half of the sphere of radius 5 centered at the origin.

I believe I am to take the integral of 1/ roe (roe^2 sin phi) d roe d phi d theta

so it is just roe times sin phi as the function but the bounds are hard for me

theta of course is from 0 to two pi

I know z goes from -5 to 0

but how to turn this into bounds in spherical coordinates???? Frostking
