What this calculator finds
A cylinder’s total surface area combines its curved side wall with its two circular ends (top and bottom). This calculator returns each part plus the combined total.
The formula
The lateral surface area is 2πrh, the area of the two circular caps is 2πr², and the total surface area is 2πr(r + h), where r is the radius and h is the height.
Common uses include estimating the material needed to wrap, paint, or label a cylindrical object such as a can, pipe, or tank. This tool is for general math and planning purposes.
