Cone Calculator

Volume, surface, and slant from radius and height.

V = ⅓πr²h. Lateral-plus-base A = πr(r+l), l = √(r²+h²). Unlike Cylinder, volume uses 1/3. Radius, not diameter. Not a pyramid.

What Cone Calculator does

V = ⅓πr²h. Lateral-plus-base A = πr(r+l), l = √(r²+h²). Unlike Cylinder, volume uses 1/3. Radius, not diameter. Not a pyramid.

The interactive controls for Cone Calculator load after this article so crawlers still read the instructions. Path /cone is the canonical address. Work happens on this device; Tool-You does not take a copy of the file or pasted text for Cone Calculator.

How to use Cone Calculator

  1. Confirm you need Cone Calculator, not Cylinder Calculator (Volume, total surface, and lateral area.). Address: /cone.
  2. Enter the numbers or dates Cone Calculator uses. Volume, surface, and slant from radius and height.
  3. Read the result as Cone Calculator defines it — not as Sphere Calculator (Sphere volume and surface from radius or diameter.). V = ⅓πr²h. Lateral-plus-base A = πr(r+l), l = √(r²+h²). Unlike Cylinder, volume uses 1/3. Radius, not diameter. Not a pyramid.
  4. Cone Calculator is an estimate in the browser, not professional advice. Radius and height ≥ 0. Includes the base. π is Math.PI. Not a cylinder or pyramid.
  5. Need a different formula? Try Sphere Calculator (Sphere volume and surface from radius or diameter.) instead of stretching Cone Calculator.

When not to use Cone Calculator

Skip Cone Calculator when a neighbor tool matches better — start with Cylinder Calculator or Sphere Calculator — or when the description already warns the job will fail. In the tool’s own words: V = ⅓πr²h. Lateral-plus-base A = πr(r+l), l = √(r²+h²). Unlike Cylinder, volume uses 1/3. Radius, not diameter. Not a pyramid.

Questions about Cone Calculator

What does Cone Calculator do that other Calculate pages on this site do not?
V = ⅓πr²h. Lateral-plus-base A = πr(r+l), l = √(r²+h²). Unlike Cylinder, volume uses 1/3. Radius, not diameter. Not a pyramid. Short version: Volume, surface, and slant from radius and height.
Does Cone Calculator upload my file or text to Tool-You servers?
No. Cone Calculator runs in this browser tab. Files stay on the device. Limit note: Radius and height ≥ 0. Includes the base. π is Math.PI. Not a cylinder or pyramid.
Should I use Cylinder Calculator instead of Cone Calculator?
Use Cone Calculator when you need Volume, surface, and slant from radius and height. Use Cylinder Calculator when you need Volume, total surface, and lateral area. They share a category (Calculate) but not the same job.
What are the limits of Cone Calculator?
Radius and height ≥ 0. Includes the base. π is Math.PI. Not a cylinder or pyramid. Also: V = ⅓πr²h. Lateral-plus-base A = πr(r+l), l = √(r²+h²). Unlike Cylinder, volume uses 1/3. Radius, not diameter. Not a pyramid.
