Sphere (ball) - closed surface, the locus of points equidistant from a given point, which is the center of the sphere. The sphere is a special case of an ellipsoid, whose three half-axis are the same.

Segment connecting the center of the sphere with its point and its length is called the radius; segment connecting two points of the ball - a chord; chord passing through the center of the sphere is called its diameter. Section of the sphere by an arbitrary plane is a circle.

At least the ball surface area among all bodies of closing this volume, and the largest closed volume for a given surface area. For this reason, the sphere frequently found in nature.

The volume of a sphere is calculated by the formula V=4⁄3πr³
