Hi friend,

Code to help in solving the problem :

class StaticCircle
{
public double radius;
double pi=3.14;
public void circle(double radius)
{
this.radius=radius;

}
public double area()
{
double a = radius*radius;
double piValue= a*pi;
return piValue;
}
public static void main(String[] args)
{
StaticCircle staticCircle = new StaticCircle ();
staticCircle.circle(10);
double i = staticCircle.area();
System.out.println("The area is " + i);
}
}
