High Quality Content by WIKIPEDIA articles! In mathematics, a dome is a closed geometrical surface which can be obtained by sectioning off a portion of a sphere with an intersecting plane. It consists of two parts: (1) a flat disk, which is joined to (2) a convex surface whose curvature is uniform and which has a circular boundary: this boundary joins with the rim of the disk. The disk can be referred to as the dome's "base". A pair of parameters are enough to describe a dome: (1) its diameter and (2) its height. The diameter refers to the size of the base, whereas the height refers to the perpendicular distance between the center of the base and the center of the concavity.
