Chapter 6, Problem 1PC

Area Class

Write a class that has three overloaded static methods for calculating the areas of the following geometric shapes:

• circles
• rectangles
• cylinders

Here are the formulas for calculating the area of the shapes.

Area of a circle:	Area = πr2
Where	π is Math.PI and r is the circle’s radius
Area of a rectangle:	Area = Width × Length
Area of a cylinder:	Area = πr2h
Where	π is Math.PI, r is the radius of the cylinder’s base, and h is the cylinder’s height

Because the three methods are to be overloaded, they should each have the same name, but different parameter lists. Demonstrate the class in a complete program.
