Formulas for calculating a sphere


Radius \(\displaystyle r=\frac{P}{2π}\)
Diameter \(\displaystyle d=\frac{P}{π}\)    \(\displaystyle =2· r\)
Perimeter \(\displaystyle P=d·π\)
Surface \(\displaystyle S=d^2·π\)     \(\displaystyle =4· r^2·π\)
Slice plane \(\displaystyle A=r^2·π\)
Volume \(\displaystyle V=\frac{d^3·π}{6}\)     \(\displaystyle =\frac{4· r^3·π}{3}\)
