About Volume of Sphere

The Volume of Sphere Calculator is a free and easy-to-use tool that helps you calculate the volume of a sphere using its radius or diameter. Whether you are a student solving geometry problems or a professional working in engineering, physics, or design, this tool provides fast and accurate results with just one click.

What is a Sphere?

A sphere is a perfectly round 3D shape in which every point on its surface is equidistant from the center. Common real-life examples include balls, bubbles, and even planets. The volume of a sphere represents the total amount of space enclosed within its surface.

Formula for Volume of a Sphere:

The standard formula to calculate the volume of a sphere is:

Volume = (4/3) × π × r³

Where r is the radius of the sphere and π ≈ 3.1416.

If you're using the diameter instead of the radius, the formula is:

Volume = (π × d³) / 6

Example Calculation:

If the radius r = 7 cm, then:

Volume = (4/3) × π × (7³) ≈ (4/3) × 3.1416 × 343 ≈ 1436.76 cm³

✅ So, the volume of the sphere is approximately 1436.76 cubic centimeters.
