Enter Information:

Radius (r) = Diameter (d) ÷ 2

Diameter (d) = 2 x Radius (r)

Circumference = 2 x π x r

Surface Area = 4 x π x r^2

Volume = (4/3) x π x r^3

## What is sphere Calculator

A Sphere Calculator is a tool that allows you to calculate various properties of a sphere based on its dimensions, such as its radius, diameter, surface area, and volume. Here are some of the calculations that can be done using a sphere calculator:

- Radius and diameter: If you know the diameter of a sphere, you can use the calculator to find its radius by dividing the diameter by 2. If you know the radius, you can find the diameter by multiplying the radius by 2.
- Surface area: The surface area of a sphere can be calculated using the formula 4πr^2, where r is the radius of the sphere. You can enter the radius into the sphere calculator to find its surface area.
- Volume: The volume of a sphere can be calculated using the formula 4/3πr^3, where r is the radius of the sphere. You can enter the radius into the sphere calculator to find its volume.
- Other calculations: Some sphere calculators may also allow you to find the circumference, chord length, or arc length of a sphere.

Using a sphere calculator can be helpful for anyone working with spheres in fields such as geometry, physics, or engineering.

## Formula for volume of sphere

The formula for the volume of a sphere is:

V = 4/3 πr^3

where V is the volume of the sphere, r is the radius of the sphere, and π (pi) is a mathematical constant that is approximately equal to 3.14159.

This formula tells us that the volume of a sphere is directly proportional to the cube of its radius. So, if you double the radius of a sphere, its volume will increase by a factor of 8 (2^3). Similarly, if you halve the radius of a sphere, its volume will decrease by a factor of 8 (1/2)^3.

## Example for volume of sphere Calculation

Suppose you have a sphere with a radius of 5 cm. To find its volume, you can use the formula:

V = 4/3 πr^3

Substituting r = 5 cm and π = 3.14159, we get:

V = 4/3 x 3.14159 x 5^3 V = 523.598 cubic centimeters (rounded to three decimal places)

So the volume of the sphere is approximately 523.598 cubic centimeters.
