You and I have a rendezvous with destiny. We will preserve for our children this, the last best hope of man on Earth, or we will sentence them to take the last step into a thousand years of darkness.
Ronald Reagan - Date: 1964



Volume and Dimensions of a Hollow Cylinder

Enter data in the h field and one of the following combinations: t and any other field, r and R, r and D, d and R or d and D.
h
t
D
d
R
r


Volume =  

Formulas:

V = Volume
D = diameter of cylinder
d = diameter of inner circle
R = radius of cylinder
r = radius of inner circle
t = thickness of cylinder
h = height of cylinder
V = 3.1416 * h * (R2 - r2)
V = 0.7854 * h * (D2 - d2)
V = 3.1416 * h * t ((2 * R) - t)
V = 3.1416 * h * t (D - t)
V = 3.1416 * h * t ((2 * r) + t)
V = 3.1416 * h * t (d + t)
V = 3.1416 * h * t (R + r)
V = 1.5708 * h * t (D + d)
