1. Add a new method to the Circle class called CalcCircum(), that returns the circumference around the circle. The formula is: Circumference = 2 * Pi * Radius (where Pi = 3.14159). Test the method to be sure it works.

2. Using the examples in this chapter as your starting point, write a program that draws an ellipse—one of the shapes we did not cover in the chapter.
