# What is formula of volume sphere and cylinder?

The volume of a sphere is given by the formula V = 4/3πr³, where r is the radius of the sphere. The volume of a cylinder is given by the formula V = πr²h, where r is the radius of the cylinder and h is the height.
In this article, we will discuss the volume of spheres and cylinders. We will derive the formulas for the volume of these shapes and then use them to calculate the volume of some specific spheres and cylinders.

## Formula for volume of a sphere

The volume of a sphere can be found using the following formula:

volume = 4/3 * π * r³

Where r is the radius of the sphere. This formula can also be used to find the volume of a cylinder, which is simply the area of one end of the cylinder multiplied by its height.

## Formula for volume of a cylinder

The volume of a cylinder can be found using the following formula:

Volume = π * r2 * h

where r is the radius of the base of the cylinder and h is the height of the cylinder.

## How to calculate the volume of a sphere and cylinder

There are two types of volume formulas for spheres and cylinders: the mathematical formula and the practical formula. The mathematical formula is more accurate, but the practical formula is easier to use.

To calculate the volume of a sphere using the mathematical formula, you 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. To find the radius, you can divide the diameter (the distance across the sphere) by 2. Once you have the radius, plug it into the following equation:

volume = 4/3 * π * r³

To calculate the volume of a cylinder using the mathematical formula, you need to know its radius and height. The radius is half of the diameter (the distance across the cylinder), and you can find it by dividing that number by 2. To get height, measure from one end of the cylinder to the other, not counting any curves or indentations. Plug those numbers into this equation:

volume = π * r² * h

## Tips for calculating volume

To calculate the volume of a sphere, you need to know the radius of the sphere. The radius is the distance from the center of the sphere to the surface of the sphere. To find the radius, you can use a ruler or a measuring tape. Once you have the radius, you can use the formula for volume of a sphere, which is:

Volume = 4/3 x π x r3

To calculate the volume of a cylinder, you need to know the radius of the cylinder and the height of the cylinder. The radius is the distance from the center of the cylinder to the surface of the cylinder. The height is the distance from one end of the cylinder to another. To find these values, you can use a ruler or a measuring tape. Once you have these values, you can use

## Conclusion

The formulas for the volume of a sphere and cylinder are very similar, with the main difference being that a sphere has an additional term for its radius. To calculate the volume of a sphere, you need to know its radius and then use the following formula: V = 4/3πr³. For a cylinder, you just need to know its height and radius, and then use the formula: V = πr²h.

These formulas are very simple and easy to use once you know the basic measurements. With a little practice, you will be able to calculate the volume of any sphere or cylinder.
Now that we have gone over the formulas for the volume of a sphere and cylinder, let’s put them to use and calculate the volume of some specific spheres and cylinders.

To calculate the volume of a sphere, we need to know its radius. The radius of this sphere is 2 inches. Plugging this into the formula, we get:

Volume = 4/3π(2)³

= 4/3π(8)

= 32/3π

= 10.667 π ≈ 10.7 π in³

To calculate the volume of a cylinder, we need to know its radius and height. The radius of this cylinder is 3 inches and the height is 4 inches. Plugging these values into the formula, we get:

Volume = π(3)²(4)

= π(9)(4)

= 36π ≈ 36 in³
