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 Sphere. 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. Sphere. In geometry, a sphereis a solid, that is absolutely round in shape defined in three-dimensional space (XYZ space). Mathematically, a sphere is defined as the set of points that is at equal distances from a common point in three dimensional space

A sphere is a geometrical object in three-dimensional space that is the surface of a ball. Like a circle in a two-dimensional space, a sphere is defined mathematically as the set of points that are all at the same distance r from a given point in a three-dimensional space. This distance r is the radius of the ball, which is made up from all points with a distance less than r from the given point, which is the center of the mathematical ball. These are also referred to as the. What is a sphere? A sphere is a three-dimensional object that is round like a ball and every point on the surface is equidistant (equal distance) from the center

For K-12 kids, teachers and parents In mathematics, the Riemann sphere, named after Bernhard Riemann, is a model of the extended complex plane, the complex plane plus a point at infinity. This extended plane represents the extended complex numbers, that is, the complex numbers plus a value ∞ for infinity. With the Riemann model, the point ∞ is near to very large numbers, just as the point 0 is near to very small numbers. The extended complex numbers are useful in complex analysis because they allow for.
