The volume of a sphere is given by the equation

, where r is the radius.
We are given the diameter of the sphere, but recall that the diameter is twice the radius:

. So the radius is half of the diameter:

.
Half of 8 cm is 4 cm.
We substitute this for r in the equation and we use 3.14 for <span>π.</span>
Area of a square with side s is

In your question, the side or s is:

And so the area of a square with that side length would be:

And using this formula:

We get that the area is:

And simplifying that we get the final answer as:
The answer would be 5.291 10 to the power of 12
