In mathematics, the Heronian mean H of two non-negative real numbers A and B is given by the formula:
It is named after Hero of Alexandria, and used in finding the volume of a frustum of a pyramid or cone. The volume is equal to the product of the height of the frustum and the Heronian mean of the areas of the opposing parallel faces.
