sphere, In geometry, the set of all points in three-dimensional space lying the same distance (the radius) from a given point (the centre), or the result of rotating a circle about one of its diameters.
The formula for the volume of a sphere is V = 4/3 πr³.
A ball is spherical; it’s shaped like a sphere — a three-dimensional version of the two-dimensional circle.
A sphere is a three-dimensional object with no vertices and edges. All the points on the surface of the sphere are equidistant from its center. Some real-world examples of a sphere include a football, a basketball, the model of a globe. Since a sphere is a three-dimensional object it has a surface area and volume.
A sphere has no sides at all. It has an infinite number of infinitesimally small surface areas, if you will. A sphere has an inner and an outer surface.
Use the 3D Tool in Illustrator
All you have to do to draw a sphere in Illustrator is to draw a circle and cut that circle into a half circle. Then add the 3D revolve effect and “presto”, you have a perfect sphere. You even have some control on the surface texture and the light source.
Sphere generally is used to represent volume specifically when the data is disproportionately large and cannot be represented properly by using and two dimensional diagram. Sphere thus is a 3-dimensional diagram.
A sphere is a geometrical figure that is perfectly round, 3-dimensional and circular – like a ball. Geometrically, a sphere is defined as the set of all points equidistant from a single point in space.
