You can put this solution on YOUR website!
You don't say whether it is a closed cylinder top and bottom
\n" ); document.write( "but I will calculate it as if it is:
\n" ); document.write( "Surface Area = 2pir^2 + 2pirh\r
\n" ); document.write( "\n" ); document.write( " = 2*pi*9^2 + 2*pi*9*6 (* is times)\r
\n" ); document.write( "\n" ); document.write( " = 508.938 + 339.292\r
\n" ); document.write( "\n" ); document.write( " = 848.23 ft^2\r
\n" ); document.write( "\n" ); document.write( "If it is open ended then the answer is just:
\n" ); document.write( " = 339.292 ft^2
\n" ); document.write( "
\n" );
