You can put this solution on YOUR website!
the volume of a cylinder is given by
volume+=+pi%2Ar%5E2%2Ah
where h is the height and r is the radius of the cylinder
this gives us
volume=pi%2A14%5E2%2A50
using a calculator gives us
volume = 30787.61 cubic cm
since 1000 cubic cm = 1 Litre
then dividing by 1000 gives the volume to be
30.787 Litres
