Surface Area of a Cylinder Find the surface area for each cylinder. Show all of your work. Round to the nearest tenth. Surface Area: The sum of the areas of all the surfaces (faces) of the threedimensional object. Cylinder: A three-dimensional object with circles forming the top and bottom bases. A cylinder is made of 2 circles and a rectangle (wraps around the object). Formula: S.A. = 2πr² + π d h Find the areas of the bases (circles) A = 2 πr² Remember there are two bases. Find the area of the rectangle (around). A = π d h Add the areas together to find the surface area. Remember to square your answer. 4
