Let W be the solid bounded by the paraboloid and the plane x = 9. Let . I know the divF is 7 here.. but after that I will need to multiply this by the volume of the region bounded above to get the flux.. am I right?

Yes, you want to integrate .
I would use cylindrical coordinates (note that I'm using x where one would traditionally use z):
So your volume is bounded by and
Spoiler:
Inner integral:
Now you have
Middle integral:
Now you have
