Question

What is the approximate volume of the sphere? Use 3.14 to approximate pi and round the answer to two decimal places if needed.

Answer 1

The volume of the sphere is given by:
$V= \frac{4}{3} \pi r^{3}$
the only thing is that you have to use the radius r in it.
[it is not given in the question]

Answer 2

No answer is possible until you tell us something about the sphere. Anything. Is it bigger than a breadbox ? Smaller than a teardrop ? We can get really mathematical about it if you'd share the sphere's radius, or diameter, or surface area. But we do need SOMEthing.
