Answer:
499,153.0 cm^3
Explanation:
The volume of a sphere is given by the formula ...
V = (4/3)πr^3
The volume of a hemisphere will be half that, or ...
(2/3)πr^3 = (2/3)π(62 cm)^3 = (158885 1/3)π cm^3
≈ 499,153.0 cm^3

Comment on this result
We have used a value of pi sufficiently accurate to give the result to 7 significant figures. If you use 3.14, you will get an answer somewhat different from this.
