a)

b )

alter this program so we create an array of five (5) circle elements. Using a loop, we'll ask the user to input the five radii and we'll store those in the array.

Write a method that takes the array as a parameter and displays the diameter, circumference and area.

. . . . . 8. Circle Class Write a Circle class that has the following member variables: radius-a double pi-a double initialized with the value 3.14159 The class should have the following member functions: Default Constructora default constructor that sets radius to 0.0 Constructor-accepts the radius of the circle as an argument setRadius-a mutator function for the radius variable getRadius-an accessor function for the radius variable getArea-returns the area of the circle, which is calculated as area = pi. radius. radius getDiameter-returns the diameter of the circle, which is calculated as diameter = radius - 2 getCircumference-returns the circumference of the circle, which is calculated as circumference = 2 pi . radius Write a program that demonstrates the Circle class by asking the user for the cir- cle's radius, creating a Circle object, then reporting the circle's area, diameter, and circumference
