Complete the code segment **to find the perimeter and area of a circle given a value of radius**.

You should use Math.PI constant in your program. If radius is zero or less than zero then print ” please enter non zero positive number “.

```
if(radius <= 0){
System.out.print("please enter non zero positive number");
}else{
//Area of Circle
area = Math.PI * radius * radius;
//Perimeter of Circle
perimeter = 2 * Math.PI * radius;
//Print the Result
System.out.println(perimeter);
System.out.print(area);
}
```
