How to determine the surface area of a cylinder

The video tutorial explains the concept of a cylinder as a type of prism, focusing on calculating its surface area. It covers the identification of the base and top, the use of pi r squared for circular areas, and the transformation of the cylinder into a rectangle to find the area of the side. The tutorial concludes with a step-by-step calculation of the total surface area, resulting in a final answer of 94.25 square yards.
