Learning to find the suface area of a cylinder

The video tutorial explains how to calculate the lateral surface area of a cylinder. It begins by discussing the area of the base, which is a circle, and how to multiply it by two to account for both the top and bottom. The tutorial then covers the area wrapped around the cylinder, described as a rectangle with a height and a length equal to the circumference of the circle. The circumference is calculated using the diameter, which is twice the radius. The final calculation involves using these measurements to find the total surface area, resulting in a value of 1005.31.
