How do you find the surface area for a cylinder?
Multiply the circumference by the length of the cylinder. You must have the radius or the diameter given (or measured) and the length given (or measured). Then use the formula: pi x D x L = Area. If the ends are to be included in the surface area, then you must calculate the area of one end (pi x R squared) and double it (because there are two ends), and add that to the previously calculated surface area.
