Calculates the outside diameter of a roll of material when the rolled length of the material, thickness
of the material, and diameter of the hole in the center or the tube on which the material is wound
are given. The number of turns on the roll is also calculated. Variations due to stretching or softness of the
material are to be ignored. An example of rolled material would be a rolled carpet or a rolled sheet of paper
from the paper mill. The length units that can be used are yard, feet, inch, meter, centimeter, millimeter
and mil. A mil is equal to one thousandth of an inch. The initial units used in the table can be changed to
any of the choices given.
