You can put this solution on YOUR website!
Basically, the area is circumference of cylinder times height.

\n" ); document.write( "Circumference = (pi)D
\n" ); document.write( "where
\n" ); document.write( "pi = 3.14
\n" ); document.write( "D = diameter
\n" ); document.write( ".
\n" ); document.write( "Circumference = (3.14)4 = 12.56
\n" ); document.write( ".
\n" ); document.write( "Area = 12.56(4) = 50.24 square feet
\n" ); document.write( "
