If you have the diameter and height of a cylindrical substance, first halve the diameter to get the radius. Then square this radius, multiply by the height and multiply by pi. The height and the radius must both be measured in the same units, e.g. metres.
Pi is equal to 3.14159265358979..... Most people use 3.14, and there is a pi button on most calculators (π).

Volume = Pir2 X height Diameter = 2r Pi = 3.1416 Solve for diameter Volume/height = 3.1416(diameter/2)2 (square root of (Volume/height/3.1416)) X 2 = diameter of the cylinder base
You cannot determine the height and diameter from just the volume because there is an almost infinite number of combinations of height and diameter that could create a particular volume.
A cone with a diameter of 10 and a height of 10 has a volume of 261.8 units3
Volume = Height * Area of Circle Area of Circle = pi*(Diameter/2)^2 Height = Diameter Volume = Diameter*(pi*(Diameter/2)^2) Volume = (pi/4)*Diameter^3 Diameter = (4/pi) * Volume ^ (1/3) Diameter = (4/3.14)*220^(1/3) ≈ 6.54 cm
A cylinder with a diameter of 24ft and a height of 11ft has a volume of 4,976.28 cubic feet.
