Write a java Circle class that should have the following static methods:

• getArea. Returns the area of the circle, which is calculated as

area = PI x radius x radius

• getDiameter. Returns the diameter of the circle, which is calculated as

diameter = radius x 2

• getCircumference. Returns the circumference of the circle, which is calculated as

circumference = 2 x PI x radius

Write a program that demonstrates the Circle class by asking the user for the circle's radius, and then reporting the circle's area, diameter, and circumference.

Sample Run:

Enter Radius: 15 Area of the Circle: 706.85775 Diameter of the Circle: 30.0 Circumference of the Circle: 94.2477
