\"v=h%2Api%2Ar%5E2\", basic formula for cylinder volume.\r
\n" ); document.write( "\n" ); document.write( "\"V=%28h%2F4%29pi%2A%282r%29%5E2\", the change described;
\n" ); document.write( "\"%281%2F4%29h%2Api%284%29r%5E2\"
\n" ); document.write( "\"%281%2F4%29%284%29h%2Api%2Ar%5E2\"
\n" ); document.write( "\"V=1%2Ah%2Api%2Ar%5E2\"
\n" ); document.write( "\"V=h%2Api%2Ar%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This situation results in \"v=V\";
\n" ); document.write( "No change in volume occurred.
