Description and formulas for the calculation of spheres
A sphere is an endless number of points equidistant from the centerpoint in a three-dimensional space
In three-dimensional space, the radius of a sphere is the segment connecting the center to any point on a sphere
The diameter is the longest distance between two points of the surface \((2·Radius)\)
\(\displaystyle r=\frac{P}{2π}\)
\(\displaystyle d=\frac{P}{π}\)
\(\displaystyle d=2· r\)
\(\displaystyle P=d·π\)
\(\displaystyle S=d^2·π\)
\(\displaystyle S=4· r^2·π\)
\(\displaystyle V=\frac{d^3·π}{6}\)
\(\displaystyle V=\frac{4· r^3·π}{3}\)
