Surface Area of Sphere Formula
Formula for surface area of a sphere:
Surface Area of Sphere = 4πr2
Surface Area of Sphere Formula using diameter:
Surface Area of Sphere = πd2
Where, r is the radius of the sphere.
Surface Area of Sphere: Formula, Derivation and Solved Examples
A sphere is a three-dimensional object with all points on its surface equidistant from its center, giving it a perfectly round shape. The surface area of a sphere is the total area that covers its outer surface.
To calculate the surface area of a sphere with radius r, we use the formula:
Surface Area of Sphere = 4πr2
This formula shows that the surface area of a sphere is directly proportional to the square of its radius. For example, if the radius of a sphere is doubled, its surface area increases by a factor of four.
