so what function do i integrate twice? and with what bounds was it

Homework Statement f(x,y,z) = g(√(x^2 + y^2 + z^2)) g(t) = t-5 evaluate ∯ f(x,y,z)ds where S is sphere x^2 + y^2 + z^2 = 9 Homework Equations The Attempt at a Solution i don't know how to go about it. can someone help me with this, how to approach this from start to end...

ok, thanks for the comments.

Homework Statement calculate net outward flux of vector field F(x,y,z)=3xy^2 i +xcosz j +z^3k, across surface solid bounded by cylinder y^2 +z^2 =1 planes x=-1, x=2 Homework Equations The Attempt at a Solution my attempt was triple integral of divF=> 3*triple integral r^3 ended...

I= [∫(0 to 1) ∫(0 to 2z) ∫(z to 1) dx dy dz] + [ ∫(0 to 1) ∫(2z to 1+z) ∫(y-z to 1) dx dy dz] 1) evaluate 2) use order dy dx dz, along with the new bounds my attempt for 1) got me an answer of -7/6 for part 2) I'm having trouble getting the correct bounds. the bounds from my attempt...
