So H V PIr2. Sometimes however we have a different set of parameters. Visual in the figure below.
Knowing the volume the radius can be computed from formula.
The formula for the volume of a cylinder is height x p x diameter 2 2 where diameter 2 is the radius of the base d 2 x r so another way to write it is height x p x radius 2. Use formulas to find the height of a cylinder given the volume or surface area. So if the volume of a cylinder is pir2h and a cone is 13 the size then the volume of a cone which uses the same formula has to have the 13rd in front. Calculating the volume of a tube essentially involves the same formula as a cylinder volumepr2h except that in this case the diameter is used rather than the radius and length is used rather than height.
