Calculate the circumference of a circle

  • 1
  • Locked
Well, we have a plan. Let's implement it. First, implement a method that calculates the circumference of a circle. To do this, you need to write the correct formula in the method and specify the arguments. But what about pi, which we know is 3.141592... and so on to infinity? We'll keep things simple: let pi = 3.14.

Can someone please clarify why you must use "int radius" for the method and why it won't work with a double? I would assume that it would be the exact opposite, the instructions even say that the result should be a fractional double.

I did not have to declare any variables for it to pass... But what I am wondering is how the answer came out as a double, when only the data type int was used?

I'm a little mixed up myself. I got the same thing you did, but for some reason, it's not accepting my code. When I say System.out.print(C), i get 31.400000000000002, but when I say System.out.print(pi), I get 3.14. Am I doing something wrong?
