In this unit, you calculated the surface area of
solid figures composed of polygons, such as
rectangles and triangles But imagine finding the
surface area of a cylinder a solid figure that has
several curved surfaces. A cylinder is made up of
two circular bases and a curved (lateral) surface
in between Develop a formula for finding the
surface area of the outside of a cylinder based on
what you know about the circumference of a circle
and the areas of circles and rectangles. (H
Think about rolling a rectangular piece of paper
into the shape of a cylinder.) Discuss your
approach and why it works
