after 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)
