Cone Calculator
Calculate volume, surface area, slant height, and dimensions
Input Values
Understanding Cones
A cone is a 3D shape with a circular base and a single apex point. The height is the perpendicular distance from base to apex, while the slant height is the distance along the curved surface.
Key Properties:
- One circular base, one apex
- Volume = 1/3 of cylinder with same base and height
- Slant height found using Pythagorean theorem
Cone Formulas
V = (1/3)πr²h
Volume
l = √(r² + h²)
Slant height
A_lateral = πrl
Lateral surface area
A_total = πr(r + l)
Total surface area
