find-circumference-circle()

Step 1: Define the Circle's Radius

First things first, we need to indicate the radius of the circle for which we want to find the circumference. We do this by declaring a variable radius and initializing it with a specific value. Let's choose a value of 5 for example.

double radius = 5;

Step 2: Declare the PI Value

Secondly, we need to declare the value of PI which is approximately 3.14. This is a requirement since the formula to calculate the circumference of a circle requires it.

final double PI = 3.14;

Step 3: Apply the Circumference Formula

Next, we have to use the formula to calculate the circumference. The formula for the circumference of a circle is 2 * PI * radius.

double circumference = 2 * PI * radius;

Step 4: Print the Circumference

Now that we have calculated the circumference, we can print it out. We will use the System.out.println() function to do this.

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

Conclusion: Full Function

Finally, here is our complete function for finding the circumference of a circle given a specific radius.

public class Main {
    public static void main(String[] args) {
        double radius = 5;
        final double PI = 3.14;
        double circumference = 2 * PI * radius;
        System.out.println("The circumference of the circle is: " + circumference);
    }
}

This function will print the circumference of a circle with a radius of 5. If you want to find the circumference for a circle with a different radius, simply modify the radius variable.
