Indeed.  At least, when tuning to A=440.

Not only could, but they _will_ tell you... :-)

Each semitone is: multiply by 2^(1/12) (approx. 1.059463094).  So 2 
up from A is multiplication by 2^(2/12).  This gives low B = 
30.86770633 Hz.

Still very low...  Only 2 semitones above the lowest pianokey.

BTW, I think it could be argued that the original "somewhere around 
27.5 Hz" still is true...
