A cylinder with a radius of 6 meters and a height of 10.5 meters has a surface area of 622.04m2
A cylinder with a height of 20 meters and a diameter of 10 meters has a surface area of 785.4m2
A cylinder that has a diameter of 10 meters and a height of 3 meters has a surface area of 251.33m2
A cylinder with a height of 10 meters and diameter of 4 meters has a surface area of 150.8m2
The surface area of the pond is measured in square meters.
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.
The curved surface area is 502.65m2
Almost two meters, on average.
Surface area = 4*pi*22 = 50.26548246 or about 50 square meters

18 meters is almost 60 feet (59.0551ft).
