About Volume of Cone

The Volume of Cone Calculator quickly computes the space inside a cone from its radius (or diameter) and height. Whether you're solving geometry problems or working on engineering, construction, or design tasks, get accurate results in one click.

What is a Cone?

A cone is a 3D shape with a circular base tapering to a point (the apex). You’ll see cones in ice-cream cones, traffic cones, funnels, and party hats. The volume is the amount of space the cone encloses.

Everyday examples:

Food – Ice cream cones and waffle cones.

Traffic – Road safety cones.

Household – Funnels for pouring liquids.

Celebrations – Party hats and decorations.

Formula for Volume of a Cone

Use the standard formula:

Volume = (1/3) × π × r² × h

Where r is the base radius, h is the height, and π ≈ 3.1416.

If you prefer the diameter, use:

Volume = (π × d² × h) / 12

Example Calculation

For r = 5 cm and h = 12 cm:

Volume = (1/3) × π × (5²) × 12
= (1/3) × 3.1416 × 300
≈ 314.16 cm³
