Homework 3
Due: Wednesday, September 22, 2004


Write a program to calculate the diameter, circumference, and area of a
circle with a radius input by the user. Assign the radius to a float
variable, and then output the radius with an appropriate message. Declare
a named constant PI with the value 3.14159. The application should output
the diameter, circumference, and area, each on a separate line, with
identifying labels. Be sure to include appropriate comments in your code,
choose meaningful identifiers, and use indentation properly.

The output from your program should look something like this:

|---------------------------------------------
|
|  Enter the radius of the circle: 4
|  Radius: 4.0
|  Diameter: 8.0
|  Area: 50.26544
|  Circumference: 25.13272
