<p>A sphere is a perfectly symmetrical three-dimensional shape, like a ball, consisting only of a curved surface. Unlike a cone, it does not have a base. The entire outer surface of the sphere is its lateral surface. Let's take an example of a basketball. The entire outer part of the basketball represents the lateral surface area of the sphere.</p>
