10. Find the surface area of a cylinder By Bill Rawlins

11. Example Calculate the surface area of: What is the radius? 13  2 = 6.5

12. Lateral Area of a Cylinder: The L.A. is the cylinder without the circular bases. L.A. = 2  rh

13. Find the Lateral Area: The radius of the base of a cylinder is 4 in. and its height is 6 in. What is the Lateral Area? L.A. = (2  r)(h) = 2  (4)(6) = 48  in 2
