Spherical structures are three-dimensional shapes that are perfectly round, resembling a ball. They have no edges or corners, making them unique in geometry. Common examples include bubbles, planets, and marbles. These structures are often found in nature and are used in various fields, including architecture and engineering, due to their strength and stability. In architecture, spherical designs can enhance aesthetics and functionality. For instance, geodesic domes are a type of spherical structure that distributes stress evenly, making them energy-efficient and durable. Additionally, spherical shapes are often used in sports equipment, such as soccer balls and basketballs, to optimize performance and handling.
