Volume of sphere formula: In this guide

In this guide, we go through all the formulas for calculating the volume of a sphere , which is defined by its radius, diameter, or circumference, with detailed explanations and examples for each method. Learn how to calculate the volume of a sphere with our easy formula explanation. Includes practical examples, derivation, and an online calculator.. A sphere is a perfectly round geometrical 3D object. The formula for its volume equals: volume = (4/3) × π × r³ Usually, you don't know the radius — but you can measure the circumference of the sphere instead, e.g., using the string or rope. The sphere circumference is the one-dimensional distance around the sphere at its widest point. Volume of a Sphere Formula In this section, you will learn the formula to compute the volume of a sphere . Volume , as you know, is defined as the capacity of a 3D object. The volume of a sphere is nothing but the space occupied by it. It can be given as:
