volume pi*r^2*h
\n" ); document.write( "20 liters=pi*625cm^2*h
\n" ); document.write( "units are liters on left, cm^2*cm on right or cm^3.
\n" ); document.write( "20 liters is 20,000 cm^3
\n" ); document.write( "Therefore,
\n" ); document.write( "20000=pi*625*h=1963.495 cm^2*h
\n" ); document.write( "divide by 1963.495=10.186 cm, height.
