Question

-radius: double -Pi double +getArea(): double +getCircumference0:double Create a constructor that takes 2 arguments radius and pi Write two methods getArea() and getCircumference that return area and ce0 circumference respectively Instantiate the class in Main() and pass the values 5.5 for radius and 3.14 for pi using the constructor of the class. Calculate the area and circumference of the circle by appropriately calling the methods from Main(). Display the area and circumference of the circle using proper print statements Input: radius = 5.5, Pi = 3.14 Output: The area of circle is: 94.985 The circumference of circle is: 34.54

Explanation / Answer

import java.util.Scanner; public class Circle { public static void main(String args[]) { // creating scanner to accept radius of circle Scanner scanner = new Scanner(System.in); System.err.println("radius:"); float radius = scanner.nextFloat(); System.out.println("pi"); float pi = scanner.nextFloat(); double area = area(radius,pi); double circumference =circumference (radius,pi) System.out.println(" The area of Circle is : "+ area); System.out.println("The circumference of circle is:"+ circumference ); scanner.close(); } public static double area(float radius,float pi) { double interest = pi * radius * radius; return interest; } public static double circumference(float radius, float pi) double circumference =2 * pi * radius; return circumference; }
