spherical surfaces

Spherical surfaces are three-dimensional surfaces that have the same curvature in all directions. They are often described mathematically using the equation of a sphere: (x-a)^2 + (y-b)^2 + (z-c)^2 = r^2 where (a,b,c) is the center of the sphere, and r is its radius. Spherical surfaces can be found in many different contexts, such as…
