The inside diameter is \"%284-2%2A%28d%2F10%29%29cm\", or the inner radius is \"2-d%2F10\" centimeters.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Volume of the hollow cylinder is \"3%2Api%2A%282%5E2-%282-d%2F10%29%5E2%29%2Acm%5E3\".
\n" ); document.write( "-
\n" ); document.write( "\"3pi%284-4%2Bd%2F5%2Bd%2F5%2Bd%5E2%2F100%29\"
\n" ); document.write( "\"3%28pi%29%282d%2F5%2Bd%5E2%2F100%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Mass will use density \"2.8g%2Fcm%5E3\" as a factor.
