**Henry**, Monday, July 12, 2010 at 2:39pm55/S = (21 3/5) / (6 7/8).

Divide 21 3/5 by 6 7/8:

55/S = 3.142/1

Solve for S

S = 55/3.142 = 17.5 cm = 6 4/5 in. = Size of hat.

C = 55 cm = (55/2.54) in = 21.6 in. =

21 3/5 in

62/S = (21 3/5) /(6 7/8)

S = 19.74 cm = (19.74/2.54) in =

7.8 in = 7 4/5 in.
