Is the quarter-sphered sized tank referring to the main tank? Or is the quarter-sphered sized tank a quarter of the size of the main tank?

anonymous · Answer

i think it is referring to the size of the main tank

Thanks for the diagram - It looks to me like the main tank is supposed to be shaped like a quarter of a sphere, but this isn't obvious at all from a 2D picture!.

You would use the equation you provided, however your final answer would need to be divided by 4, since we only have a quarter of a sphere.
