As a cylinder is a three dimensional object with volume = {pi}r2h (with r the radius of the circular end and h to height of the cylinder), I presume you mean its surface area:
There are 2 circular ends with area {pi}r2 each.
Plus the curved surface which has one dimension the height of the cylinder, the other the circumference of the circular end, so its area is 2{pi}r x h.
So the total surface area of a cylinder
= 2 x {pi}r2 + 2{pi}r x h
= 2{pi}r(r + h).

Call the length of the cylinder 'L', and the radius of the circular ends 'R'. The surface area of the 'pipe' part is [ 2 pi R L ]. If you also want the area of the ends, each one is [ pi R2 ].
A cilinder has: 3 faces, 0 corners and 2 edges.
The formula is π * r2 * h... Where π is the value of Pi, r is the radius of the cylinder and h is the height.
No When a right cylinder is viewed at right angle to its axis the projected form can be a square or a rectangle, which have 4 right angles. The same applies if the cylinder is cut through on any plane parallel to its axis.
