Sphere

A sphere is a three-dimensional shape that is perfectly round, with all points on its surface equidistant from its center. It is a type of solid geometric figure and is often referred to as a "ball". The surface area and volume of a sphere are important properties that can be calculated using specific formulas.

Properties of a Sphere:

• Surface Area: The surface area of a sphere is given by the formula: 4πr², where r is the radius of the sphere.
• Volume: The volume of a sphere is given by the formula: (4/3)πr³, where r is the radius of the sphere.
• Center: The center of a sphere is the point equidistant from all points on its surface.
• Radius: The radius of a sphere is the distance from the center to any point on its surface.
• Diameter: The diameter of a sphere is the distance across the sphere through its center, and it is twice the length of the radius.
