Answer 1

Answer:

Explanation:

import java.util.*;

class circle

{

public static void main(String ar[])

{

Scanner sc=new Scanner(System.in);

double r,circum,area;

System.out.println("Enter the radius of circle: ");

r=sc.nextDouble();

circum = (2)*(22/7)*(r);

area = (22/7)*r*r;

System.out.println("Circumference is: "+ circum);

System.out.println("area is: "+ area);

}

}
