Understanding the Context
How the Volumes Compare: A Clear, Neutral Explanation
To determine the ratio, start with the volume formulas. The volume of a sphere with radius $ y $ is $ \frac{4}{3}\pi y^3 $. The hemisphere’s volume is half that of a full sphere of radius $ 3y $, so it is $ \frac{1}{2} \cdot \frac{4}{3}\pi (3y)^3 = \frac{2}{3}\pi \cdot 27y^3 = 18\pi y^3 $.
Now divide the sphere’s volume by the hemisphere’s:
$$
\frac{\frac{4}{3}\pi y^3}{18\pi y^3} = \frac{4}{3} \div 18 = \frac{4}{54
