Spheres

A sphere is a perfectly round, three-dimensional object where every point on its surface is equally distant from its center, like a sphere-shaped ball or globe. Think of it as the three-dimensional equivalent of a circle. Spheres are common in nature and design, such as planets, bubbles, and certain fruits. Unlike other shapes, they have no edges or corners, and their curvature is constant everywhere. Because of this uniformity, spheres have unique properties, such as the shortest possible surface distance between two points on their surface.
