formula for finding the surface area of a cylinder
Example 1: Find the lateral surface area of a cylinder with a base radius of 3 inches and a height of 9 inches. L. S. A. = 2 Ï (3)(9) = 54 Ï inches 2. â 169.64 inches 2. The general formula for the total surface area of a cylinder is T. S. A. = 2 Ï rh + 2 Ï r 2.
