# Program to find the surface area of the cylinder

Program to find the surface area of the cylinder on fibonacci, factorial, prime, armstrong, swap, reverse, search, sort, stack, queue, array, linkedlist, tree, graph etc.

## Program to find the surface area of the cylinder

### Explanation

In this program, we have a cylinder with the given radius and height. We need to find its Surface area.

A cylinder is a three-dimensional geometrical figure/container with straight parallel sides and two circular cross-sections. So we have three surfaces of the cylinder.

The surface area of two circular cross-sections = 2( Π × r × r )

The surface area of parallel sides = Circumference times the height = 2 Π × r × h

Total Surface Area of Cylinder = 2( Π × r × r ) + 2 Π × r × h = 2 Π (r + h)

### Formula

```Surface Area of Cylinder = 2 Π  (r + h)
Here, r is the radius and h is the height of the cylinder.
Π ( pi ) = 22/7 = 3.14
```

### Algorithm

1. Define the values of radius and height.
2. Insert into given formula.
3. Print the Surface Area of Cylinder.

O(1)

### Python

```r = 2.0  #radius
h = 5.0 #height
surfacearea = (2*22*(r + h))/7 #calculation
print ("Surface Area Of Cylinder : ");
print (surfacearea); #prints surface area
```

Output:

```Surface Area Of Cylinder :   44.0
```

### C

```#include<stdio.h>
int main()
{
float r,  h, surfacearea;
r=2.0;
h = 5.0;
surfacearea = (2*22*(r + h))/7;
printf("\n\n Surface Area of Cylinder is : %f", surfacearea);
return (0);
}
```

Output:

```Surface Area of Cylinder is: 44.00000
```

### JAVA

```            public class test
{
public static void main(String args[])
{
float r, h, surfacearea;
r = 2;
h  = 5;
surfacearea = (22*r*(r+h))/7;
System.out.println("Surface Area of Cylinder is: "+surfacearea);
}
}
```

Output:

```Surface Area of Cylinder is:  44.000000
```

### C#

```using System;
class Program
{
static void Main()
{
float r, h, surfacearea;
r  = 2;
h = 5;
surfacearea = (22*r*(r+h))/7;
Console.WriteLine("Surface Area of Cylinder is:"+surfacearea);
}
}
```

Output:

```Surface Area of Cylinder is:  44
```

### PHP

```<?php
\$r = 2.0;
\$h =  5.0;
\$surfacearea =(22*\$r*(\$r+\$h))/7;
echo("Surface Area Of Cylinder is = ");
echo(\$surfacearea);
?>
```

Output:

```Surface Area Of Cylinder is = 44
```
