A sphere (from Greek σφαῖρα —sphaira, "globe, ball") is a geometrical object in threedimensional space that is the surface of a ball (viz, analogous to the circular objects in two dimensions, where a "circle" circumscribes its "disk") Like a circle in a twodimensional space, a sphere is defined mathematically as the set of points that are all at the same distance r from a given. The surface area of a sphere is given by the formula Where r is the radius of the sphere In the figure above, drag the orange dot to change the radius of the sphere and note how the formula is used to calculate the surface area This formula was discovered over two thousand years ago by the Greek philosopher Archemedes.
