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.
Instructions: Fill out your name under programmer name, the date and time you started the assignment, the date and time you completed the assignment, total hours you dedicated to the assignment (should be a minimum of 1 1/2 hours for a good quality, well done assignment – rules of academic honesty apply for this), and any constructive comments you have about the assignment (could be things you liked about the assignment; or if you had the opportunity to do the assignment all over again, what would you do differently?)
