Find the perimeter of a cylinder
  • Difficulty Level : Easy
  • Last Updated : 13 Apr, 2021

Given diameter and height, find the perimeter of a cylinder.
Perimeter is the length of the outline of a two – dimensional shape. A cylinder is a three – dimensional shape. So, technically we cannot find the perimeter of a cylinder but we can find the perimeter of the cross-section of the cylinder. This can be done by creating the projection on its base, thus, creating the projection on its side, then the shape would be reduced to a rectangle.
 

Formula : 
Perimeter of cylinder ( P ) = ( 2 * d ) + ( 2 * h )
here d is the diameter of the cylinder 
h is the height of the cylinder
Examples : 
 

Input : diameter = 5, height = 10 
Output : Perimeter = 30

Input : diameter = 50, height = 150 
Output : Perimeter = 400

 

 



C++




// CPP program to find
// perimeter of cylinder
#include <iostream>
using namespace std;
 
// Function to calculate perimeter
int perimeter(int diameter, int height)
{
    return 2 * (diameter + height);
}
 
// Driver function
int main()
{
    int diameter = 5;
    int height = 10;
     
    cout << "Perimeter = ";
    cout<< perimeter(diameter, height);
    cout<<" units\n";
     
    return 0;
}

Java




// Java program to find
// perimeter of cylinder
import java.io.*;
 
class GFG {
 
    // Function to calculate perimeter
    static int perimeter(int diameter, int height)
    {
        return 2 * (diameter + height);
    }
     
    /* Driver program to test above function */
    public static void main(String[] args)
    {
        int diameter = 5;
        int height = 10;
        System.out.println("Perimeter = " +
                         perimeter(diameter, height)
                                       + " units\n");
    }
}

// Function to calculate perimeter
function perimeter($diameter, $height)
{
    return 2 * ($diameter + $height);
}
 
    // Driver Code
    $diameter = 5;
    $height = 10;
     
    echo("Perimeter = ");

<script>
 
// javascript program to find
// perimeter of cylinder
 
// Function to calculate perimeter
    function perimeter(diameter, height)
    {
        return 2 * (diameter + height);
    }
 
// Driver Function
 
         let diameter = 5;
        let height = 10;
        document.write("Perimeter = " +
                         perimeter(diameter, height)
                                       + " units\n");
     
    // This code is contributed by susmitakundugoaldanga.
</script>

Output : 
 

Perimeter = 30 units
