What is a Sphere ?

A sphere is a perfectly round geometrical object in three-dimensional space, similar to a ball. All points on the surface of a sphere are equidistant from the center. It is defined by a single parameter, its radius.

The formula for calculating the volume (V) of a sphere is given by:

V = 4/3 x π x r3

where:

  • V is the volume of the sphere
  • π (pi) is a mathematical constant approximately equal to 3.14159265359
  • r is the radius of the sphere.

To use the formula, simply plug the radius of the sphere, and then calculate the result. Remember to use consistent units for your measurements
