    I don't see what you are referring to... the closest formula is the formula for the volume of a cylinder:

    Видим...

    Ја још увек не знам где сте добили ову формулу, али то је формула за запремине цилиндра, подељен 3363 коју ја не знам где сте добили.

    Могу ли питати за оно питање које сте добили од те формуле? Будете могли да шаљете целу питање да ли је могуће?

    ::::::::::::::::::::
    I see...

    I still don't know where you got this formula, but it is the formula for the volume of a cylinder, divided by 3363 which I don't know where you got.

    Could I ask in what question you got that formula from? Can you post the entire question if possible?

    Pa Srbi su pametan narod I to nije formula za zapreminu cilindra vec za drugaciju geometrisku figuru,

    Нисам рекао супротно... Ја само питам где сте добили ту формулу, или да ли имате слику фигура?

    :::::::::

    I didn't say the opposite... I'm just asking where you got that formula, or do you have a picture of the figure?

    Ок, али ја немам појма шта је око формуле. Као што сам раније рекао, најближи формула је запремина цилиндра. Што се зашто је то подељено са 3363, не знам. Можда је то због фактор конверзије...

    ::::::::::
    Ok, but I don't have a clue of what the formula is about. As I said earlier, the closest formula is the volume of a cylinder. As to why it is divided by 3363, I don't know. Maybe it's due to a conversion factor...

    Interesting - but can you tell us where this comes from, and why it was included in your volume formula?

    I've been thinking about this. Here's one possible scenario where you would get this factor in your volume equation. If you consider a parabaloid of height h and base radius R, its volume is:



    Now if that paraboloid had material removed from it in the shape of a second narrower parabaloid, also of height h but with base radius = , the volume of material removed is:



    So subtracting one from the other yields:



    Perhaps this is the shape you are looking for?
