# Cylinder
The Cylinder class represents a cylindrical object whose height and radius is known. The class provides methods to calculate the volume and surface area.
Problem Statement
Write the code for the Cylinder class that meets the following requirements:
- The Radius and Height properties should have a private set.
- Should get the radius and the height
- Should calculate the volume and the surface area
Volume of a Cylinder = pi * r^2 * h
$Surface Area of a Cylinder = 2 * pi * r^2 + 2 * pi * r * h
$
