A cone is a 3D shape with a circular base that tapers to a single point called the apex. The calculations for the volume and surface area of a cone depend on the radius of the base and the height of the cone.
Use our Cone Calculator to quickly calculate the volume, surface area, slant height, and other properties of a cone. Whether you are working on a math project, engineering design, or any application involving cones, this tool will give you accurate results in seconds.
A cone is a 3D geometric shape with a circular base that tapers smoothly to a point called the apex or vertex. The slant height is the distance from the base to the apex, measured along the side of the cone, while the height is the perpendicular distance from the base to the apex.
V = (1/3) π r² h
Where:
V = Volume
r = Radius of the base
h = Height of the cone
A = π r² + π r l
Where:
A = Surface area
r = Radius of the base
l = Slant height
Aₗ = π r l
Where:
Aₗ = Lateral surface area
r = Radius of the base
l = Slant height
l = √(r² + h²)
Where:
l = Slant height
r = Radius of the base
h = Height of the cone
