Volume and Surface Area of a Spherical Segment

Enter data in the h field and either the c or r fields.
r
h
c


Volume =  
Surface area =  

Formulas:

V = Volume
A = area of spherical surface
r = radius
h = height
c = width of chord
V = 3.1416 * h2 * (r - (h / 3))
V = 3.1416 * h * ((c2 / 8) + (h2 / 6))
A = 2prh
A = 6.2832 * r * h
A = 3.1416 * ((c2 / 4) + h2)
c = 2 * sqrt(h * (2r - h))
r = (c2 + 4h2) / (8 * h)
