SUMMARY
The volume to surface area ratio of a sphere is calculated using the formulas V = (4/3)πr³ for volume and A = 4πr² for surface area. The resulting ratio V/A simplifies to r/3, indicating that the ratio is directly proportional to the radius of the sphere. This straightforward relationship allows for quick calculations when the radius is known. Understanding this ratio is essential for applications in geometry and physics.
