About the Cone Volume Calculator
A cone's volume is one-third that of a cylinder with the same base and height. Its surface area includes the circular base plus the curved lateral surface. Radius and height each have their own unit selector, and so does every result — the calculator converts everything automatically.
Formulas: Volume = (1/3)πr²h · Surface Area = πr(r + slant height), where slant height = √(r² + h²)
