A sphere is a 3D geometric figure that has a round shape. All points on the surface of the sphere are an equal distance from its center. Below are some real-life examples of spheres. A basketball, the Earth, and an orange are all examples of geometric figures that have the shape of a sphere.
Aug 3, 2023 · If a sphere is cut into 2 equal halves, each half is known as a hemisphere or half-sphere or semi-sphere. (hemi in Greek and semi in Latin). Parts and Properties.

4 days ago · 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, 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 components and properties of a sphere are analogous to those of a circle.
Nov 8, 2014 · The sphere $S^0$ is a pair of points, the sphere $S^1$ is the circle, the sphere $S^n$, when $n>2$, is sometimes called a hypersphere. The volume of the sphere $S^n$ (the length when $n = 1$, the surface when $n = 2$) is given by the formula \[v(S^n) = \frac{2\pi^{(n+1)/2}}{\Gamma((n+1)/2)}R^n;\] in particular,
