You can put this solution on YOUR website!
Wait,are you asking whats the formula for a cylinder?? If so here it is:\r
\n" ); document.write( "\n" ); document.write( "pi:(3.14;22/7;or pi symbol.your choice)so anyways its \"2B%2BCh\"( the 2 BASES+CIRCUMFERENCE x HEIGHT)so the real translation of that formula is this formula :\"2xPixR%28radius%29%5E2%2B2xPixRxH\"\r
\n" ); document.write( "\n" ); document.write( "example: A cylinders radius is 4cm and its height is 10cm.
\n" ); document.write( "Formula:\"2xPixR%5E2+%2B+2xPixRxH\"\r
\n" ); document.write( "\n" ); document.write( "Solution: \"2xPix%284%29%5E2+%2B+2xPix%284%29x%2810%29\"=352cm <-----Answer;just plug ALL THAT in your calculator and remember,USE 3.14 or 22/7,or the Pi symbol for Pi.!
