You calculate the circumference of the cylinder. Once you know that, you can just multiply by the height, since effectively the side of a cylinder is just a rectangle rolled up.
2(pi)(r)(h)=the area of the curved surface
1. Find the surface area of the whole cylinder 2. Find the area of one of the two circles on either end of the cylinder 3. Multiply the circle's area by two and subtract their area from the total surface area 4. Now you have the surface area of an unclosed cylinder!
Curved surface area includes the area of the length of the cylinder only whereas surface area includes the two bases as well...
It called the curved surface area. There is no special name for it.

The curved surface are is: pi*diameter*height
Curved surface area of a cylinder excluding the two end pieces = 2*pi*radius*height in square units.
The surface area of the curved part of a cylinder is pi*r2h, where r is the radius and h is the height. If the height is tripled, the area becomes pi*r2(3h), or 3(pi*r2h). So if the height is tripled, the area of the curved surface is also tripled.
2 x Pi x radius x height or length = curved surface area
The label is placed on the curved surface area of the cylinder. Its area can be found using the formula A = 3.14dh where d is the diameter and h is the height of the can. It is rectangular in shape.
The curved surface area of this cylinder is 251.33 units2
If cylinder radius and cylinder length are known : (pi = 3.141592654 . . . ) > Surface area = ( (2 * pi * radius) * length )
