The surface area of a cylinder can be derived from the area of rectangle. If you 'unroll' a cylinder you have a shape of a rectangle, similar to a sheet of paper. The width of the rectangle will be the height of the cylinder and the length of the rectangle will be the circumference of the cylinder end.
So, Area = length * width
where, width = height of cylinder & length = circumference of cylinder end = PI*(Diameter of cylinder)
Therefore,
surface area of a cylinder = (PI)*(diameter of cylinder)*(height of cylinder)
Hope that helps!

The surface area of this cylinder is 2,111.15 square feet.
The lateral area of a right cylinder is curved surface that connects the two bases. The surface area is the total area of the curved surface and the bases.Lateral Area: The lateral area of a right cylinder with radius r and height h is L = 2pirh.Surface Area: The surface area of a right cylinder with lateral area L and base area B is S = L + 2B, or S = 2pirh + 2pir^2.
The surface area of a cylinder if the radius is 3 and the height is 11 equals 263.9 square units.

The cube's surface area consists of six squares; you can simply add the area of each of the squares. Note that each of the squares has the same size.
