## Area of A Sphere

The scale of a sphere is decided by its radius (the distance from the middle of the sphere to any points on its surface). It can be described as the set of all points situated from the distance "r" on a point center. It's absolutely symmetrical and has no edges or vertices.

The formula to find the area of the surface of a sphere is given below:

$$\text{Area}\;=\;4πr^2$$

Where,

**r**is the radius of the surface area of sphere.- π the value of pi is 3.14 or 3.14159. It is the ratio of the circumference of any circle to the diameter of the circle.

## What is Volume of a Sphere?

A sphere is a set of points in space that are located on given distance r from the center.

The volume is the amount of space occupied by any 3 dimensional solid. Volume is measured in cubic units such as in³, ft³, cm³, m³ etc. Be sure that all of the measurements must be in the same unit before calculating the volume.

## Volume of a Sphere formula

The volume V of a sphere is 4/3 times of radius cubed and pi.

$$\frac {4}{3} πr^3$$

The volume of a hemisphere is 1/2 the volume of the related sphere.

$$=\;\frac {4}{3} πr^3$$

Where r is the radius of the sphere. Since the 4, 3 and pi are constant values, this simplifies to approximately

$$4.19r^3$$

By rearranging the formula given above, you can find the radius:

$$r\;=\;\sqrt[3]{\frac{3v}{4π}}$$

where v is the volume of a sphere.

## Circumference of a Sphere

The Circumference of a circle or a sphere is equal to 6.2832 times more of the Radius. The Circumference of a circle or a sphere is equal to 3.1416 times more than the Diameter.

The formula to find the Circumference of a sphere is mentioned below:

$$C\;=\;2πr$$

Circumference can be obtained using circumference calculator.

## Diameter of a Sphere

The Diameter of a sphere is equal to 2 times more than the Radius. Formula to calculate the diameter of the sphere is:

$$D\;=\;2r$$

## Things to recall

- Surface area of sphere = 4πr
^{2} - Volume of a sphere = 4/3 πr
^{3} - You only need to know the radius to calculate both the volume and area of a sphere.
- Surface area problems answers should always be in square units
- Volume problems answers should always be in cubic units
