You are told that the volume of a sphere is given by V=pie d3/4, where V is the volume and d is the diameter of the sphere. Is this equation dimensionally correct? Use SI unit analysis to find out.:confused: :confused:

well the dimension of d is length. [L]
3/4 and pi are dimensionless so the dimension of 3/4d^3 is [L]^3 which is the dimensions of volume.
Please clarify the purported formula, do you mean:Quote:

Yeah, I missed that
if its d, then its wrong
if its d^3 then its fine.
I think she meant this one.Quote:
