Answer:
254.0 cm³
Explanation:
The formula for the volume of a sphere in terms of its radius is ...
V = (4/3)πr³
Then the formula for the volume of a hemisphere in terms of its diameter is ...
V = (1/2)(4/3)π(d/2)³ = (π/12)d³
The volume of the hemisphere is ...
V = (π/12)(9.9 cm)³ ≈ 254.024 cm³
The volume is about 254.0 cm³.
