use the volume of a cylinder twice
\n" ); document.write( "\"VolumeOfCylinder+=+pi%2Ar%5E2%2Ah\"
\n" ); document.write( "h = 0.2\r
\n" ); document.write( "\n" ); document.write( "So
\n" ); document.write( "\"V+=+%28pi%2A1.5%5E2%2A0.2%29+-+%28pi%2A1.3%5E2%2A0.2%29\"\r
\n" ); document.write( "\n" ); document.write( "solve for that
\n" ); document.write( "
\n" );
