Cone Calculator

    Calculate cone volume, base area, lateral surface area, total surface area, slant height, radius, height, diameter, and net-sector angle.

    Enter all linear dimensions in the same unit. Use the diameter mode when diameter is your known base value.
    example: radius 1, height 2

    Right circular cone calculator

    The English SERP for cone calculator combines radius, height, slant height, volume, curved surface area, and total surface area. This tool keeps those outputs together so one calculation can answer both volume and area tasks.

    l is slant height, r is radius, and h is vertical height.

    Cone volume is one third of the matching cylinder volume.

    Lateral area is the curved side of the cone.

    Use one length unit throughout a calculation. Linear outputs use that unit, surface areas use square units, and volume uses cubic units.
