# How to find volume of a sphere with radius

## How do you find volume with radius?

**Sphere Formulas in terms of radius r:**

- Volume of a sphere: V = (4/3)πr. …
- Circumference of a sphere: C = 2πr.
- Surface area of a sphere: A = 4πr.

## What is the volume of the sphere of radius?

Volume of a sphere of radius,

**r=34πr3**.## How do you find the volume of sphere?

## Why is the volume of a sphere 4 3?

Volume of a sphere = 4/3 πr

^{3} The difference between the two shapes is that a circle is a two-dimensional shape and **a sphere is a three-dimensional shape** which is the reason that we can measure the Volume and area of a Sphere.

## How do you calculate volume?

Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is

**length × width × height**.## Which is the formula for the volume of a sphere with diameter D?

FAQs on Diameter of a Sphere Formula Using Volume

The volume of a sphere (V) in terms of its radius (r) is V = (4/3) π r^{3}. If d is its diameter, we have d = 2r. From this, we get r = (d/2). Substituting this in the volume formula, the volume of a sphere in terms of diameter is **V = (πd ^{3})/6**.

## How do you calculate the volume of a sphere without a calculator?

## How do we find the radius of a circle?

**How to Find the Radius of a Circle?**

- When the diameter is known, the formula is Radius = Diameter/ 2.
- When the circumference is known, the formula is Radius = Circumference/2π.
- When the area is known, the formula for the radius is Radius = ⎷(Area of the circle/π).

## How did Archimedes calculate the volume of a sphere?

Archimedes

**used an inscribed half-polygon in a semicircle, then rotated both to create a conglomerate of frustums in a sphere**, of which he then determined the volume.## How do you find volume with radius and height?

The volume of cylinder is the amount of space in it. It can be obtained by multiplying its base area by its height. The volume of a cylinder of base radius ‘r’ and height ‘h’ is

**V = πr**.^{2}h## How do you find the volume of a sphere with only the circumference?

## How do you calculate volume for kids?

Volume is the amount of physical space a 3D object takes up. It is the 3D equivalent of area for a 2D shape. It is measured in cubic measurements, like cm³. This can be found by

**multiplying its length × height × width**.## How do you calculate volume in cubic meters?

**CBM Calculation Formula**

- Length (in meter) X Width (in meter) X Height (in meter) = Cubic meter (m3)
- We can define dimensions in Meter, Centimeter, Inch, Feet.

## How do you work out volume in litres?

The first thing you need to do is multiply the length by the width by the height. That gives the number of cubic millimetres. To calculate the number of litres, you then

**divide that number by a million**.## How do you determine the volume of a circle?

**Volume of a cylinder**

- V = A h.
- Since the area of a circle = π r 2 , then the formula for the volume of a cylinder is:
- V = π r 2 h.

## How do you calculate volume in primary school?

You can work out the volume of a shape by

**multiplying height × width × depth**.## What is this volume?

In mathematics, ‘Volume’ is

**a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface**. The unit of volume is in cubic units such as m^{3}, cm^{3}, in^{3}etc. Volume is also termed as capacity, sometimes.## Does a circle have a volume?

**No, a circle doesn’t have a volume**. A circle is a two-dimensional shape, it does not have volume. A circle only has an area and perimeter/circumference.

## How do you calculate volume and capacity?

The most common unit of volume is centimetres cubed (cm3).

**One centimetre cubed will hold one millilitre of fluid or another substance**. 1000 cm3 will hold one thousand millilitres of fluid or another substance. Remember that 1000 mL = 1L, so 1L = 1000 cm3.## What are 3 ways to calculate volume?

## What are the two formulas for volume?

Let’s learn!

Geometric Shape Name: | Volume Formula: |
---|---|

Cube | Volume = a³ , where a is length of each side. |

Rectangular Prism | Volume = l × w × h , where l is length, w is width and h is height. |

Sphere | Volume = 4/3 πr³ , where r is the radius. |

Cylinder | Volume = πr²h , where r is the radius and h is the height. |

## Can volume be measured in liters or cubic meters?

Volume is the measure of the 3-dimensional space occupied by matter, or enclosed by a surface, measured in

**cubic units**. The SI unit of volume is the cubic meter (m^{3}), which is a derived unit. Liter (L) is a special name for the cubic decimeter (dm^{3}).
