Answer 1

Question:

Write a program in java to enter the radius of a circle and to calculate its circumference.

Answer:

import java.util.*;

public class Scanner

{

Scanner in =new Scanner(System.in);

float r,c;

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

r=in.nextFloat();

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

System.out.println("The circumference of the circle is="+r);

}

}

Explanation:

We know that, the area of a circle is= 2πr

But in programming we can put 'π' directly so we should put the value of 'π'  directly that is, 22/7.

Since the value of the radius and also of the area can be in decimal point so, we should input the values in float data type.
