document.write( "I totally agree with Tutor @IKLEYN that the shortest solution is best. I also agree that the shortest and easiest\r\n" );
document.write( "method to get to the answer is to EQUATE the 2 VOLUMES. However, \"%281.5%2F2%29%5E2%2A16\" = 9. So, 9 = \"36R%5E2\"\r\n" );

document.write( "                                     Therefore, radius of each small candle, or  \r\n" );
document.write( "                                     As such, diameter of each small candle = 2R = 2(.5) = 1 cm.
