Sphere is a perfectly symmetrical space in which all points on the surface are the same distance **“r”** from the centre. It has **no** edges or

vertices (corners) and It has one **surface** .

## Sphere Surface Area Formula

**The surface area of a sphere can be calculated using the following formula, where r is the radius of the sphere**

**Surface Area = 4 × π × r ^{2}**

## Sphere Volume Formula

**Volume = (4/3) × π × r ^{3}**
