A sphere is a 3D shape that has the same measure of circumference as a circle of the same radius. The surface area of a sphere is the total area of its curved surface, and it can be calculated using the formula:
Surface area of a sphere = 4πr²
where:
The surface area of a sphere is a measure of how much space is covered by its curved surface. The larger the radius of the sphere, the larger its surface area will be.
The surface area of a sphere is used in many applications, such as calculating the area of a spherical object for use in physics or engineering, or finding the amount of paint needed to paint a sphere
