Several orders of magnitude?  I deliberately neglected pi and
produced an estimate of a billioneth of a metre squared 
(i.e. 10^-9 m^2)  -- which was the same as your answer!

I guess you thought I meant "a (billioneth of a metre) squared"
but I meant ""a billioneth of a (metre squared)", which is implied
since the answer has to be in units of area.  Perhaps it would 
have been clearer if I'd said a billioneth of a square metre.

Cheers,

PS metre (UK) = meter (US)
