Explanation:

1. A hemisphere is half of a sphere. So, the volume of a hemisphere is half ($\frac{1}{2}$) the volume of a sphere.
2. The formula for the volume of a sphere is $V=\frac{4}{3}\pi r^{3}$, where $r$ is the radius. So, to calculate the volume of a sphere, you need to know the radius.
3. The space inside a 3 - D object is its volume. For a sphere, the space inside is its volume.
4. As mentioned in the formula $V = \frac{4}{3}\pi r^{3}$, to calculate the volume of a sphere, you need to know the radius of the sphere.

Answer:

1. half ($\frac{1}{2}$)
2. radius
3. volume
4. radius
