The circumference of that cylinder would be 31.4156 meters, and with a height of 4 meters, the outside surface of the sides would be 125.66 square meters.

Does a cylinder have both an inside and outside surface? There is no thickness at all to the sides. Maybe it needs to be doubled, to be 251.32 square meters so we get both inside and outside surface, but I think not.

A cylindrical *prism* would have a top and bottom, each having a surface of 78.54 square meters, for a total of 282.74 square meters.
