Question

For an sphere what would be the formula

Answer 1

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

Answer 2

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.
