I got this so far... I need to make a area2... then I have to divide area2/area1.... I then need a println statement for it.... Can anyone help? How do i make an area2, and what would the println statement for dividing the two be?

To calculate the ratio of two areas, you need to calculate the second area and then divide it by the first area. Here's how you can modify your code to calculate area2 and the ratio:

1. Declare a new variable for the second radius, let's say radius2:

```
int radius2 = 30;
```

2. Calculate the second area using the formula A = π * r^2:

```
double area2 = PI * radius2 * radius2;
```

3. Calculate the ratio by dividing area2 by area:

```
double ratio = area2 / area;
```

4. Finally, print the ratio using a println statement:

```
System.out.println("The ratio of the areas is: " + ratio);
```

Your updated code should now look like this:

```
public class Circumference {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
;
final double PI = 3.14159;

int radius = 10;
double area = PI * radius *radius;
double circum = 2 * PI * radius;

System.out.println("The area of a circle with radius " + radius + " is " + area);
System.out.println("The circum of a circle with radius " + radius + " is " + circum);

radius = 20;
area = PI * radius * radius;
circum = 2 * PI * radius;

System.out.println("The area of a circle with radius " + radius + " is " + area);
System.out.println("The circum of a circle with radius " + radius + " is " + circum);

int radius2 = 30;
double area2 = PI * radius2 * radius2;
double ratio = area2 / area;

System.out.println("The ratio of the areas is: " + ratio);
}
}
```

Now when you run the code, it will calculate the ratio of the areas of circles with radius 20 and 30, and print the result.
