Surface area is area of the side plus the 2 "end caps":
The end caps are %28pi%29r%5E2 each, so they contribute +2%28pi%29r%5E2+
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)
+A+=+2%28pi%29+rh+%2B+2%28pi%29+r%5E2+
Plugging in r=6cm and h=16cm:
+A=2%28pi%29%286%29%2816%29+%2B+2%28pi%29%286%5E2%29+
+A=192%28pi%29+%2B+72%28pi%29+
+A=264%28pi%29+
+A=829.38046+
Answer: +Area+=+829.38+ cm%5E2
