Question

. To accept radius of a circle, calculate area and print the result
in the following format: Radius is
Area is
Repeat the whole process n times. java​

Answer 1

import java.util.Scanner;

public class Area {

public static void main(String[ ] args) {

Scanner sc = new Scanner(System.in);

// Accepting number of iterations.

System.out.print("Enter number of iterations - ");

int iterations = sc.nextInt( );

for (int i = 0; i < iterations; i++) {

// Accepting Radius.

System.out.print("Enter Radius - ");

float radius = sc.nextFloat( );

// Printing Radius and Area.

System.out.printf("Radius - %f%n Area - %f%n", radius, Math.PI * radius * radius);

}

}
