Answer: The volume of a sphere with a diameter of 12.5 is 1022.6538 cubic units.
Explanation:
First of all, we need the formula of the volume of a sphere which is:
V=4/3πr^3
Where r stands for radius.
We are given the diameter which is 12.5
To find the radius you must take the diameter and divide by two, because the radius is half of the diameter.
12.5/2 = 6.25
So the radius is 6.25.
Now lets plug it in the formula.
V=4/3π(6.25)^3
And simplified you get that the volume is:
1022.6538 units^3
