Spheres
Spheres Spheres are three-dimensional closed surfaces.A sphere is a set of points in three-dimensional space equidistant from a point called the center. The radius of the sphere is the distance from the center to the points on the sphere. Spheres are not polyhedra. Of all shapes, a sphere has the smallest surface area for its volume.The volume of a sphere is … [Read more...] about Spheres
