Volume of Sphere
The volume of a sphere is a space, which we can fill in and which is bounded by a spherical surface. For example, when we want to count how much water we could insert into a spherical water container. To calculate the volume of a sphere, we need to know a length of its diameter or radius and use a formula of a volume of a sphere. The elementary unit of a volume is one cubic metre, it means the third power of one metre (1 m3).
Volume of Sphere - formula
Volume of Sphere = 1/6 × Ludolph's number × diameter3
4/3 × Ludolph's number × radius3
V = 1/6 × π × d3 = 4/3 × π × r3
