Sphere Surface Area Calculator

    Calculate sphere surface area from radius, diameter, great circle circumference, known surface area, or volume.

    This calculator returns the full sphere surface area, not a hemisphere, dome, or spherical segment.

    Sphere surface area from radius or diameter

    The English intent is the full outside area of a sphere, not a hemisphere or dome. The calculator supports radius, diameter, great circle circumference, surface area, and volume inputs.

    S — sphere surface area; r — radius.

    S — sphere surface area; d — diameter.

    V — sphere volume; r — radius.
