The ⁠ ⁠-sphere is a circle, the circumference of a disk (⁠ ⁠-ball) in the two-dimensional plane. The ⁠ ⁠-sphere, often simply called a sphere, is the boundary of a ⁠ ⁠-ball in three-dimensional space.

Four-dimensional space (4D) is the mathematical extension of the concept of three-dimensional space (3D). Three-dimensional space is the simplest possible abstraction of the observation that one needs only three numbers, called dimensions, to describe the sizes or locations of objects in the everyday world.

An n-ball is a ball in an n-dimensional Euclidean space. The volume of a n -ball is the Lebesgue measure of this ball, which generalizes to any dimension the usual volume of a ball in 3-dimensional space .

2016年6月15日 · It can be estimated by using the Monte Carlo approach and choosing random sets of 4D coordinates and determining their distance from the origin. Dividing this by 16 gives the estimated volume of the 4-D ball with radius = 1, and from there we can solve for the constant.
