**Reiny**, Sunday, January 13, 2013 at 9:46pmafter 1st breath , diameter = 5cm

after 2nd breath , diamieter = 1.2(5) =

after 3rd breath, diameter = 5(1.2)^2=

(this question is physically unrealistic, Mary would be inserting the same amount of volume, which would show up with smaller and smaller increases in the diameter, certainly not a steady 20% increase each second)
