V = Volume|
S = area of cylindrical surface a = 1/2 width of segment
b = distance from the center line of the circle to the edge*
r = radius
d = diameter
|Area of base =||
p * r2 - Area of Segment**|
|Area of base =||Area of Segment***|
|V =||((2/3) * a3 + b * Area of base) * (h / (r + b))|
|S =||((a * d) + (b * length of arc****)) * (h / (r + b))|
*If the base area is less that one-half the base circle, b should be negative.
**If b is positive.
***If b is negative.
****Portion of Circumference (this is calculated in the program).
