# Who calculated volume of sphere?

The answer to this question is a little bit complicated. The volume of a sphere was first calculated by an Greek mathematician named Archimedes. He did this by finding the amount of water that was displaced when he placed the object in water.

This method was later refined by other mathematicians and scientists, who came up with more accurate ways to calculate the volume of a sphere. Today, we use formulas that take into account the radius of the sphere and its surface area. So, while Archimedes may have been the first to calculate the volume of a sphere, there have been many people who have contributed to the development of this formula.

## The History of the Volume of a Sphere

The volume of a sphere was first calculated by the Greek mathematician Archimedes in the 3rd century BC. He did this by filling a cylindrical container with water and measuring the amount of water that was displaced. From this, he was able to calculate the volume of the sphere.

This method was later refined by other mathematicians, including Pierre de Fermat and Blaise Pascal. However, it wasn’t until the 19th century that an exact formula for the volume of a sphere was derived. This was thanks to the work of Carl Friedrich Gauss, who developed a general formula for calculating volumes that could be applied to any shape.

## The Mathematical Formula for the Volume of a Sphere

The mathematical formula for the volume of a sphere is 4/3πr³. The Greek letter π (pronounced “pie”) is a mathematical constant that is equal to 3.14159. r is the radius of the sphere, which is the distance from the center of the sphere to any point on its surface. The radius can be measured in any unit of length, such as inches, feet, centimeters, or meters.

## How to Calculate the Volume of a Sphere

There are a few different ways to calculate the volume of a sphere. The most common way is to use the formula V = 4/3πr³, where r is the radius of the sphere. To use this formula, you will need to know the radius of the sphere. The radius is the distance from the center of the sphere to any point on its surface.

Another way to calculate the volume of a sphere is to divide it into smaller pieces, such as slices or pyramids. You can then calculate the volume of each small piece and add them all together to get the total volume of the sphere. This method is often used when the radius of the sphere is not known.

To calculate the volume of a slice, you will need its thickness (h), height (r), and width (w). The thickness is how thick each slice is, while the height and width are measured from the center of the slice. The formula for calculating the volume of a slice is V = πh(r + w/2)². To calculate the volume of a pyramid, you will need its height (h), base length (l), and base width (w). The formula for calculating the volume of a pyramid is V = 1/3hlw.

You can also estimate the volume of a sphere by using everyday objects. For example, an orange can be used to estimate

## Examples of the Volume of a Sphere

When calculating the volume of a sphere, there are a few key things to keep in mind. The first is that the volume of a sphere is equal to 4/3 times the radius of the sphere cubed. This means that if you know the radius of the sphere, you can easily calculate its volume. The second thing to keep in mind is that theradius of a sphere is equal to its diameter divided by 2. This means that if you know the diameter of a sphere, you can also calculate its radius and then its volume.

Now that we know how to calculate the volume of a sphere, let’s look at some examples. If we have a sphere with a radius of 3 meters, we can calculate its volume like this:

Volume = 4/3 x 3^3

Volume = 36 meters^3

This means that thevolume of our sphere is 36 cubic meters. Let’s look at another example. This time, let’s say we have a sphere with a diameter of 10 meters. We can calculate its radius like this:
