surely you know by now that the volume of the parts are
cone: 1/3 πr^2 h
hemisphere: 2/3 πr^3
and their areas are:
cone: πrs = πr√(r^2+h^2)
hemisphere: 2πr^2
so plug in your numbers.
You could easily have discovered these formulas online. Just sayin'

1. Volume of cone + volume of
hemisphere
1/3 πr^2h + 2/3 πr^3
898.3 is the answer
hemisphere
1/3 πr^2h + 2/3 πr^3
898.3 is the answer
