Question

Q1-Write a program to find the product of two numbers x and y,where x=120 and y=300. Q2- Create a program to calculate and print the circumference and area of a circle​

Answer 1

Q1 :

import java.util.*;

public class product

{

public static void main (String args[])

{

int x = 120 , y = 300;

System.out.print("Product of x and y : "+ x * y);

}

}

Q2 :

import java.util.Scanner;

public class Area_Circumfrence

{

public static void main(String[] args)

{

float r, area, circum;

Scanner sc = new Scanner(System.in);

System.out.print("Enter the Radius of Circle: ");

r = sc.nextFloat();

area = (float) (3.14*r*r);

circum = (float) (2*3.14*r);

System.out.println("\nArea = " +area);

System.out.println("Circumference = " +circum);

sc.close();

}

}
