@jdoe0001 that doesn't help much

jdoe0001 · Answer

well, I think it does, assuming you know what a diameter is :|, is pretty much all you'd need

espex · Answer

You know the volume of your sphere is calculated with $$Volume = \frac{4}{3} × π × r^{3}$$So if your diameter is doubled, then your radius is also doubled. This gives you a new equation of $$Volume = \frac{4}{3} × π × (2r^{3})$$

thought so too, but all you'd really need is the formula :|, and maybe a few clarifications if needed at all
