<p>A cylinder and a cone are both 3-dimensional shapes with circular bases. The surface area of these shapes is the total area covered by their outer surfaces. The surface area of a cylinder includes its two circular bases and its curved surface, while the surface area of a cone includes its curved surface and its base. In this article, we will learn about the surface area of both a cylinder and a cone.</p>
