Subject: Re: surface area of cones and cylinders

The surface area of cones is equal to the area of the base, plus the lateral area of the cone. The surface area of the base is equal to pi x radius2. The lateral area is equal to pi x radius x length, where legnth is the slant height of the cone. So, the surface area of a cone is equal to pi x radius2 + pi x radius x length.
