### Cylinder Volume Calculator

Now, we want to find the find volume? We know the Radius and height. Then put both values in the Calculator and Find the volume. In example, diameter is give then, Radius= Diameter/2
We know the cylinder volume formula i.e.

Radius

Height

Volume of Cylinder

### Formula to Find Volume, Surface Area of a Cylinder

Formula to find the volume of a Cylinder

We know the Height(h) and Radius(r) of the following cylinder then,
 Cylinder

We can find the Volume of a Cylinder by,

V = πr2h

where,
V = Volume of Cylinder
π (pi)= 3.14159265358979 but we generally take 3.14 (constant)
r = Radius of circular surface of Cylinder (as shown in above figure)
h = Height of Cylinder (as shown in above figure)

Finding Area of Surface:

 Surface area of Top and Bottom
The area of the top = πr2
The are of the bottom = πr2

 Surface area of Side
Area of the Side = 2πrh

Therefore total  Surface area can be given by,
A = 2πrh +2πr2

A = 2πr(r+h)

### Geometry Shape: Cylinder, Definition of Cylinder

What is actually Cylinder?

One of the Three Dimensional geometric shape. Shape of the Cylinder as shown in the Following figure:

Where,
r= radius of Cylinder
h= height of Cylinder

A Cylinder is known as Kulindros in Greek.
