Every circle has a center and a radius. Given the radius, we can determine the circles area and circumference. Given the center, we can determine its position in the x-y plane. The center of a circle is a point in the x-y plane. Design a class, circleType, that can store the radius and center of the circle. Because the center is a point in the x-y plane and you designed the class to capture the properties of a point in Programming Exercise 3, you must derive the class circleType from the class pointType. You should be able to perform the usual operations on a circle, such as setting the radius, printing the radius, calculating and printing the area and circum- ference, and carrying out the usual operations on the center.
