4*Pi*R squared, it may seem like a hard formula, but if you think about it it is pretty easy to understand.

There are many ways to do it, but to me the easiest way to do it is to square the radius ( half of the distance from the other point of a circle) then multiply it by Pi then multiply it by 4.


Radius= 2cm.

R squared is 4 cm. (2*2) multiplied by pi equals 12.56 (pi=3.14) then multiply that by 4 to get your final answer which is 50.24.

Not only is the formula hard, it is completely wrong!

The volume of a sphere is 4/3*pi*R3 where R is the radius.

Because it is a measure of the volume, the linear measures appearing in it MUST be to the third power (cubed). Thus, the fact that the previous answer gave R2 was a clear indication of an error. The example then multiplies by R2 twice making it R4!
