In this video we'll learn how to find the surface area of right circular Cones. A right circular cone is a cone whose base is a circle and that has a right angle (90-degree angle) between the base of the cone and it's altitude. When we find the surface area of a cone, we'll use the formula for the area of a circle in order to find the area of the base of the cone, and then we'll use the slant height of the cone in order to find the surface area of the lateral face.
