Surface area is area of the side plus the 2 \"end caps\":\r
\n" ); document.write( "\n" ); document.write( "The end caps are \"%28pi%29r%5E2\" each, so they contribute \"+2%28pi%29r%5E2+\"
\n" ); document.write( "The area of the side part is circumference * height or \"+2%28pi%29rh+\" (to visualize this imagine you take the side of a can, cut it vertically and then \"unroll\" it so it lies flat, forming a rectangle of \"h+x+2%28pi%29r\")\r
\n" ); document.write( "\n" ); document.write( "\"+A+=+2%28pi%29+rh+%2B+2%28pi%29+r%5E2+\"\r
\n" ); document.write( "\n" ); document.write( "Plugging in r=6cm and h=16cm:\r
\n" ); document.write( "\n" ); document.write( "\"+A=2%28pi%29%286%29%2816%29+%2B+2%28pi%29%286%5E2%29+\"
