A sphere (from Greek σφαῖρα, sphaîra) [1] is a geometrical object that is a three-dimensional analogue to a two-dimensional circle. Formally, a sphere is the set of points that are all at the same distance r from a given point in three-dimensional space. [2]

3 days ago · A sphere is defined as the set of all points in three-dimensional Euclidean space that are located at a distance (the "radius") from a given point (the "center"). Twice the radius is called the diameter , and pairs of points on the sphere on opposite sides of a diameter are called antipodes .
Sphere definition: a solid geometric figure generated by the revolution of a semicircle about its diameter; a round body whose surface is at all points equidistant from the center. Equation. See examples of SPHERE used in a sentence.
Properties of a sphere. In Geometry, a sphere is defined as the set of all points in space that are equidistant from a fixed point (the center) of the sphere. Radius. A radius, r, of a sphere is a line segment from the center of the sphere to any point on the sphere's surface.
Aug 3, 2023 · Definition. A sphere is a three-dimensional symmetrical solid. Its shape is spherical which means completely round. It can be defined as the set of all the points equidistant from a fixed point, known as the center. The diagram below shows the shape of a sphere. Sphere.
A sphere is a round, three-dimensional object without any edges or vertices. every point on its surface is equal to its centre. The shape has an equal distance between any point on the surface and the centre of the sphere. Let’s find out spheres, their definition, properties, and real-world examples in detail.
