## What Is a Sphere?

A sphere is a round, three-dimensional object that has no vertices or edges, unlike other three-dimensional shapes. Every point on its surface is equidistant from the center. In other words, the distance between the sphere’s center and any point on its surface is the same.

A sphere is a circular, three-dimensional solid figure in geometry. It comprises a collection of points connected in three dimensions by a single common point at equal distances.

A tennis ball, a basketball, a soap bubble, etc., are some examples of spheres. The following are a sphere’s main components:

The radius is the length of the line segment drawn from any point on the sphere’s surface to its center.

### Circumference

The circumference of a sphere is its length measured along its great circle. The circumference of the dotted circle in the illustration below, or the cross-section of the sphere that contains its center, is depicted.

## Surface Area of a Sphere

The surface area of a sphere is the space that the sphere’s outer surface occupies. It has a square unit of measurement. The following is the formula to determine the surface area of a sphere:

$\text{Surface Area of Sphere} = 4\pi r^{2}$

## Volume of a Sphere

The amount of space a sphere can occupy is determined by its volume. Cubic units are used to measure it. The following is the volume formula for the sphere:

$\text{Volume of Sphere} = \frac{4}{3} \pi ^{3}$
