Cone Volume Calculator

    Calculate cone volume, slant height, surface areas, liters, and net sector angle from radius or diameter and height, with reverse modes.

    The calculator solves a right circular cone. Height is perpendicular to the base; slant height runs along the side.

    Cone volume from radius and height

    English search intent focuses on a right circular cone. The practical calculator should accept radius or diameter, distinguish vertical height from slant height, and show surface-area outputs.

    r is base radius and h is vertical height.

    l is slant height.

    Common outputs

    OutputUse
    VolumeSpace inside the cone.
    Slant heightSide length needed for lateral area.
    Lateral areaSide surface without the base.
    Total surface areaSide surface plus the circular base.
    Net sector angleGeometry of the cone's side net.
    Do not enter slant height as vertical height. Use the radius-and-slant-height mode when the side length is known.
