Volume of a sphere

Why is the volume of a sphere
\( \frac{4}{3}πr^3\) ?

Hi @RZ923!
Nice question! Not so many people even wonder about where this formula came from! However, to be able to prove the formula of the volume of a sphere, you should know about integrals, how to use them and where they came from. Before you reach that point, you will first gain lots of other knowledge and experience. Then you will be even able to prove it by yourself.

@nastya thanks
