/* Eva Goins
 * Chapter 6
 * Description: Utilizes class Circle to create a circle. Gets
 *      user input for the circle radius in order to use methods
 *      getArea, getDiameter, and getCircumference to calculate
 *      the area, diameter, and circumference respectively.
 *      Displays the area, diameter, and circumference after
 *      calculating.
