33.Methods need help cant find where i did wrong



Oops, try again. Your code caused a TypeError when trying to call .perimeter(). Make sure you have properly defined the perimeter method. Use the .area() method as a guide. Here's the error message: TypeError: c.perimeter is not a function

Replace this line with your code. 

function Circle (radius) {
    this.radius = radius;
    this.area = function () {
        return Math.PI * this.radius * this.radius;
    // define a perimeter method here
this.perimeter = function () {
    return Math.PI * 2 * this.radius;


never mind solved it
// define a perimeter method here


this part made it didnt work
