It will be of little avail to the people, that the laws are made by men of their own choice, if the laws be so voluminous that they cannot be read, or so incoherent that they cannot be understood
Alexander Hamilton - Date: 1788



Volume and Dimensions of a Cone

Enter data in either the r and d fields and in either the h or s fields.
r
d
h
s


Volume =  
Surface area =  

Formulas:

V = Volume
S = area of conical surface
h = height
s = length of side
r = radius
d = diameter
V = (3.1416 * r2 * h) / 3
V = 1.0472 * r2 * h
V = 0.2618 * d2 * h
S = 3.1416 * r(sqrt(r2 + h2))
S = 3.1416 * r * s
S = 1.5708 * d * s
s = sqrt(r2 + h2)
s = sqrt((d2 / 4) + h2)
