## 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 4π*r*^{2}; the volume of a sphere is 4/3π*r*^{3}.
