## Area Od Sphere

The text describes the surface area of a sphere, which is defined as the total area covered by its outer surface. It is the smallest surface for a given volume and encloses the largest volume among all closed surfaces. The formula for the surface area is 4 π r^2 or π times the diameter squared. There are online calculators available to determine the surface area, circumference, volume, and radius of a sphere with known variables.

The area of a sphere is calculated using the formula A = 4πr^2, where 'A' represents the surface area and 'r' represents the radius of the sphere.
