The volume is:
\n" ); document.write( "\"PI%2Ar%5E2%2Ah%2F2\" where h is the length. It's divided by 2 since it's a hemisphere.
\n" ); document.write( "V = \"PI%2A.645%5E2%2A4%2F2\" (in cubic meters)
\n" ); document.write( "V = 2.614 cubic meters
\n" ); document.write( "Water weighs 1 gram per cc, or 1 kg per liter. A cubic meter is 1000 liters.
\n" ); document.write( "V = 2614 liters, so the weight is:
\n" ); document.write( "W = 2614 kg
\n" ); document.write( "
\n" );
