the volume of a cylinder is given by
\n" ); document.write( "\"volume+=+pi%2Ar%5E2%2Ah\"
\n" ); document.write( "where h is the height and r is the radius of the cylinder
\n" ); document.write( "this gives us
\n" ); document.write( "\"volume=pi%2A14%5E2%2A50\"
\n" ); document.write( "using a calculator gives us
\n" ); document.write( "volume = 30787.61 cubic cm
\n" ); document.write( "since 1000 cubic cm = 1 Litre
\n" ); document.write( "then dividing by 1000 gives the volume to be
\n" ); document.write( "30.787 Litres
\n" ); document.write( "
\n" );
