Find the area of the top and bottom circle, then, multiply the height of the cylinder by the circumference of one circle. Add that all together to get the answer. Example: Height; 5 in. Diameter (of...
there is no area. it is called surface area which is=2(pi)rh+2(pi)r(squared).this is the total surface are of a SOLID cylinder. for an open or hollow one it is =2(pi)rh+(pi)r(squared)
