An oceanographer is analyzing the movement of ocean currents and models a small spherical region of water with a radius of $y$ meters. Nearby, there is a hemisphere-shaped region with a radius of $3y$ meters. What is the ratio of the volume of the spherical region to the volume of the hemisphere?

To decode these forces, oceanographers create detailed models of water movement—often starting with fundamental geometric shapes like spheres and hemispheres. Imagine a small spherical water region measuring $y$ meters across, while a nearby hemisphere-shaped area expands to a vast radius of $3y$ meters. What does the math reveal when comparing the space contained within this sphere to the blended volume of this hemisphere? Understanding liquid volume
