How to find the volume of a sphere given the diameter

Step-by-step explanation:

The volume of a sphere is given by

V=4/3πr^3

Then, if we are given the diameter

We need to find radius from the given diameter, diameter is the line that cut the sphere into two equal parts, while radius is a line that comes from the center of the sphere to the surface of the sphere.

The radius is the half of a diameter

r=d/2

So, the given diameter will be divided by 2 before inserting it into the volume of a sphere.

Note also the π is a constant and it is often given as 3.142 or 22/7.

r^3 means r*r*r.

Volume of sphere = (4πr^3) / 3
