Cone Calculator
Free cone calculator. Calculate volume, surface area, slant height from radius and height. Includes all formulas and visual diagram.
Cone Formulas
Volume: V = (1/3)πr²h
Slant Height: s = √(r² + h²)
Lateral Surface Area: Alateral = πrs
Base Area: Abase = πr²
Total Surface Area: A = πr² + πrs = πr(r + s)
Note
A cone's volume is exactly 1/3 of a cylinder with the same base and height.
