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 ) =

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"` `);` ` ` `}` `}` ` ` `// This code is contributed by Gitanjali.` |

**Output :**

Perimeter = 30 units
