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```
