For an sphere:

Diameter = (2) x (radius)

Radius = (1/2) x (diameter)

Surface area = (4) x (pi) x (radius)²

Volume = (4/3) x (pi) x (radius)³

A sphere's volume formula is :

\({ V }_{ sphere }=\frac { 4 }{ 3 } \cdot \pi \cdot { r }^{ 3 }\)

and surface are formula is:

\({ V }_{ a }=4\cdot \pi \cdot { r }^{ 2 }\)

Where r is radius.
