👉 Unspherical is a concept in spherical geometry, specifically a method of determining the surface area of a sphere from its radius. It involves dividing the surface into smaller, concentric spheres and then summing up their areas to determine the total surface area of the sphere. The process starts with choosing any point on the surface of the sphere as the center of the sphere, and then drawing lines connecting this point to each of the four points that are equidistant from the center. These lines will form
