How it works
This page assumes a right circular cone.
- Volume: 1/3 × π × r² × h
- Slant height: √(r² + h²)
- Lateral area: πrl
- Total surface area: πr² + πrl
Examples
- r = 3, h = 5 → cone volume and slant height
- r = 1, h = 1 → small cone example
- r = 10, h = 20 → larger cone

FAQ
- What does this cone volume calculator compute?
It computes cone volume, slant height, lateral area, and total surface area from radius and height.
- What formula is used for cone volume?
The formula is V = 1/3 × π × r² × h.
- How do you find slant height?
For a right circular cone, slant height is l = sqrt(r² + h²).
- What is the total surface area?
Total surface area = πr² + πrl, where l is the slant height.
- Are calculations stored?
No. Everything runs locally in your browser.
