Write a Java program that generates and prints circle-related values: diameter, circumference and area. To calculate these values, you need the radius and a constant value pi.

Declare and initialize the radius of the circle as r=5.5, and the constant value pi should be declared and initialized to a value of 3.145.

Use the following formulas to calculate the diameter, circumference and area:

Diameter= radius+radius

Circumference=2*pi*radius

Area=pi*radius*radius
