Cone Surface Area Calculator

    Calculate cone total surface area, lateral area, base area, slant height, height, radius, diameter, and volume.

    Total and lateral cone surface area

    English search results for cone surface area distinguish total surface area, lateral area, and base area. This page accepts radius or diameter with either vertical height or slant height, then returns all of those surface-area parts.

    r is radius and ell is slant height.

    Lateral area excludes the circular base.
