task103 • Circle length

alxjspalma

I keep getting an error when I Submit task:

Function circleLength should return the length of the circle given the radius

I haven't change anything because I can't find any errors: (helper.js)

const PI = 3.14159265359;
export const circleLength = (radius) => {
  return PI * 4 / radius;
}

When I press Run your code I get two numbers: (solution.js)

import { circleLength } from './helper.js';
console.log(circleLength(5));
console.log(circleLength(12));

Is it the variable PI that starts with a capital letter? I changed it and still got the error.
Is it the math that is wrong (PI * 4 / radius)? If it's that I'm really going to need your help 🤣
Can you help me find the problem?

Hey, Alex. Thank you for the well-formatted and clear question.

Is it the math that is wrong (PI * 4 / radius)?

Yes. It's the main problem here. The correct formula is PI * 2 * radius.
