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.
