How to find the surface area of a cone

The video tutorial explains how to calculate the surface area of a cone. It begins with finding the area of the base, which is a circle, using the formula pi r squared. The tutorial then introduces the formula for the lateral area of a cone, which is pi times r times l, where l is the slant height. The instructor demonstrates how to plug in the values for r and l to calculate the total surface area. The final result is calculated using a calculator, and the importance of including units, specifically squared centimeters, is emphasized.
