About Volume of Hemisphere

The Volume of Hemisphere Calculator is a free, easy-to-use tool that computes the volume of a hemisphere from its radius (or diameter). Whether you're studying geometry or working in engineering, architecture, physics, or 3D modeling, you’ll get quick and accurate results in one click.

What is a Hemisphere?

A hemisphere is half of a sphere, formed by slicing a sphere through its diameter. Real-world examples include Earth’s northern/southern hemispheres, domes, and bowls. The volume measures how much space half a sphere encloses.

Everyday examples:

Geography – Earth’s hemispheres.

Architecture – Domes and curved roofs.

Kitchen – Bowls and ladles.

Design – 3D models and simulations.

Formula for Volume of a Hemisphere

Use the standard formula:

Volume = (2/3) × π × r³

Where r is the radius and π ≈ 3.1416.

Using diameter instead of radius:

Volume = (π × d³) / 12

Example Calculation

For r = 6 cm:

Volume = (2/3) × π × (6³)
= (2/3) × 3.1416 × 216
≈ 452.39 cm³
