Calculating the volume of the cylinder is not really difficult, even when such geniuses as Archimedes, Ptolemy, Al-Kashi, Ludolph van Ceulen, Sharp, Rutherford, Ferguson, and other, we may now say hundreds of scholars, have worked to refine Ludolph's number. This tool can also calculate the volume of pipes, tubes, trusses, thus, both the volume of the cavity and the volume of the full shell material.
Also useful:

• in household calculation of the volume of cylindrical containers (casseroles, pots)
• you can calculate the volume of cylinders in an engine when the stroke will be the height and bore diameter
• calculating the volume of pools or wells of circular plan - enter the values in decimetres and the results will be in litres
