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

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");
    }
}

Output :

Perimeter = 30 units

Time complexity: O(1)

Auxiliary Space: O(1)
