Write a program that defines the Circle class and uses it to create objects.

The program should constructs three circle objects with radius 1, 25, and 125 . The program displays the radius and area of each of the three circles. It then changes the radius of the second object to 100 and displays its new radius and area. Create 2 classes:

1- TestSimpleCircle Class

2- SimpleCircle

Create 3 objects:

1- Circle1 with default radius

2- Circle2 with radius 25

3- Circle3 with radius 125
