not getting correct values

CENGAGE I MINDTAP Programming Exercise 4-6 | Instructions Circle 5 Create a class named circle with fields named radius , dianeter and area . Include a constructor 6 td ch that sets the radtus to 1 and sp 9 16 calculates the other two values. Also include methods named setRadtus and getRadius() The setRadius() method not only sets the radtus , but it also calculates the other two values. (The diameter of a circle is twice the 12 radius and the area of a circle is pi multiplied by the square of the radius. Use the Hath dass P constant for this calculationa Grading

Answer 1

the question says setRadius method will set the diameter and area as well. Your version doesn't do that. Please replace your setRadius method with the one below:

    public void setRadius(double r){
        radius=r;
        diameter=2*radius;
        area=Math.PI*radius*radius;
    }

Please also change your getDiameter function. Make it only return the diameter. Remove the line

diameter=2*radius;
