Sphere Formulas
There are three main formulas for a sphere, including formulas for the diameter of the sphere, the surface area of the sphere, and the volume of the sphere. All of these formulas are listed in the table below.
Diameter of Sphere | D = 2r |
Surface Area of Sphere | A = 4πr2 |
Volume of Sphere | V = (4/3)πr3 |
Sphere Formulas
The sphere is a round 3D object. Unlike other 3D shapes, the sphere has no vertices or edges. The distance from the center of the sphere to any point on the surface is the same. In geometry, a sphere is a three-dimensional figure with a round shape. From a mathematical point of view, it is a combination of a set of points connected by common points equidistant in three dimensions. Examples of spheres include basketball, soap bubbles, and tennis balls.
