What is a Sphere?

  • Surface Area: The surface area of a sphere is proportional to the square of its radius. This is why the surface area of a larger sphere is much greater than that of a smaller one.
  • Center of Gravity: The center of gravity of a sphere is at its center, making it an ideal shape for objects that need to maintain balance.
