////////////////////////////////////////////
See attached figure.
AL = AE + EL = AP/2 = 2.75/2
CM = CD + DM = CN/2 = 3.25/2
AE = h1
CD = h2
EL = DM = ?
CM - AL = CD + DM - (AE + EL)
=> CD - AE = h2 - h1 = (3.25-2.75)/2 = 0.25

=> h2 - h1 = ...

Solution Summary

The dimensions of a form roller are found using trigonometry. A diagram is included with this solution.
