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