    flux integrals

    Compute the flux integral

    for the following vector fields and surfaces.

    1. F(r) = 3z i + 2x j + y k, where the surface S is the upper half of the hemisphere x2+y2+ z2 = 9; the normal direction is upward.
    I am probably making a calculation mistake, or couldn't figure out the trigonometry part to evaluate the integral at the end?
    Is there someone with time to tell me the right answer so I can check my work,

    appreciated,

    Here is what I found:
