[Math] Triple integrals using spherical coordinates with a sphere not centered at the origin

multivariable-calculus

Let $F(x,y,z)=(6x,-2y,5z)$ a vector field and $S$ the surface of the sphere centered at $(1,0,1)$ e radius $5$. Find the flux of $F$ across the surface $S$.

I want to use the Gauss theorem, and my problem is when i use spherical coordinates how can i found the bounds for $\rho$, $\psi$ if the sphere is not centered at the origin.

Thank you

Hint.

Why don't you use integration by substitution using a translation in order to reduce the problem to one where the sphere is centered at the origin?
