Sphere Formulas – Volume and Surface Area
Volume and surface area formula for Sphere are as follows:
Volume of a Sphere (V) = 4/3πr3
Surface Area of a Sphere (A) = 4πr2
Where,
- π is a Mathematical Constant
- r is Radius of Sphere
Formulas for diameter, area, and volume are given in the following table:
Sphere | Formula |
---|---|
Surface Area (A) | 4πr2 |
Volume (V) | (4/3)πr3 |
Circumference of Circle | 2πr |
Diameter (d) | d = 2r |
Radius (r) | r = d/2 [Given the diameter] |

Sphere: Definition, Formulas, Examples, Shapes, Properties
Sphere is a three-dimensional object that is perfectly round and symmetrical in shape. It is a set of points in 3-D space that are all equidistant from a fixed point(center). The distance from the center to any point on the surface of the sphere is the same, and this distance is called the radius. A sphere is defined in 3 axis whereas a sphere is defined only in 2 axis.
In this article, we have explained everything about the Sphere from the Definition of Sphere, Volume, and Surface Area Formula, to Real-life Examples of Spheres. Let’s get a closer look at Sphere in Detail.
