2.28 (Diameter, Circumference and Area of a Circle) Write an application that inputs from the user the radius of a circle as an integer and prints the circle’s diameter, circumference and area using the floating-point value 3.14159 for π. Use the following formulas (r is the radius): diameter = 2r circumference = 2πr area = πr2. Do not store the results of each calculation in a variable. Rather, specify each calculation as the value that will be output in a System.out.printf statement.
