Answer:
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
