Its a java program :-
Q1)

Import java.util.*;
Class cls
{
Public static void main()
{
Scanner sc = new Scanner(System.in);
System.out.println(“Enter your radius”)
double a = sc.nextDouble();
double b = ((22/7)*a*a;
double c = (2*(22/7)*a;
System.out.println(“Area :” +b);
System.out.println (“circumference :” +c);
}
}
