# Cone
The Cone class represents a conical object whose height and base radius is known. The class provides methods to determine the volume and surface area with this information.
Problem Statement
Write the code for the Cone 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 Cone = 1/3 * pi * r^2 * h
$Surface Area of a Cone = pi * r^2 + pi * r * sqrt(r^2 + h^2)
$
Note that the portion sqrt(r^2 + h^2)
$ is known as the slant height.
Use the following class diagram when creating your solution.
