What are the surface area, lateral area, and volume of a sphere?

A sphere is a set of points equidistant from a central point (a center); a sphere in two dimensions is a circle. In the case of a sphere, the lateral and surface areas are the same; therefore, a sphere with a radius r has a surface/lateral area of 4πr2; the volume of a sphere is 4/3πr3.
