The volume of a sphere is found by multiplying four-thirds by pi by radius cubed. The Greek mathematician Archimedes first derived this formula. He also found that the surface area of a sphere equals four by pi by radius... More »

Find the volume of a sphere by solving for the equation V=4/3*pi*r^3, where V is volume, r stands for radius and pi is 3.1459. Cube the radius, and multiply that number by pi and 4/3 for the volume. Pi delineates the rel... More »

A sphere is a solid geometric figure defined as the set of all points equidistant from a common center point. It is perfectly symmetrical, and its surface is uniformly curved, without any edges, vertices or faces. It is ... More »

A sphere has no faces, edges or vertices. By definition, it is a curved three-dimensional geometric figure whose surface is defined as the set of all the points equidistant from its center point. More »

A vertex is a corner on a polygon, polytope or polyhedron, and when faces, facets or edges of an object come together, a vertex forms; however, because a sphere features no meeting points, it has no vertices. Even though... More »
