Answer 1

Answer:

import java.util.Scanner;

public class circle

{

public static void main(String args[])

{

System.out.println("Area and circumference of circle calculator :)");

Scanner in = new Scanner(System.in);

double r, c, a;

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

r=in.nextInt();

c=2*3.14*r;

a=3.14*r*r;

System.out.println("The area of circle is :"+a);

System.out.println("The circumference of circle is :"+c);

}

}

circumference.

Program Starts

import java.util.Scanner;

class CircleDemo

{

public static void main(string args[ ])

{

Scanner sc = new Scanner (System.in);

System.out.println("enter the radius:");

double radius = sc.nextDouble ( );

double area = Math.PI * ( radius * radius );

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

double circumference = Math.PI * 2 * radius;

System.out.println("circumference of the circle is:" +circumference);

}

}
