You can put this solution on YOUR website!
Formula for the surface area of a cylinder is:
\n" ); document.write( "\"A=2%28pi%29r%5E2%2B2%28pi%29rh\"
\n" ); document.write( "You are given r and h, so just plug and chug:
\n" ); document.write( "\"A=2%28pi%29%283%5E2%29%2B2%28pi%29%283%29%288%29\"
\n" ); document.write( "Simplifying:
\n" ); document.write( "\"A=2%28pi%29%289%29%2B2%28pi%29%2824%29\"
\n" ); document.write( "\"A=18%28pi%29%2B48%28pi%29\"
\n" ); document.write( "\"A=66%28pi%29\"
\n" ); document.write( "You can plug that into your calculator to get a numerical answer. Don't forget to round it off.
