it says do pie(radius * 2) in the formula for area and this is exactly how i have it. "this.area = Math.pow(3.14, radius * 2)" but its saying im wrong.

Circle.js
```class Circle {
this.area = Math.pow(3.14, radius * 2)
this.circumference = 2 * 3.14 * radius ;
}

}

const circ = new Circle();
``` The instructions say `the formula for area is area = π*r^2`, which assumes that you know to apply the exponent first. Perhaps they should have written it as: `π * (r^2)`. What the code above is doing is actually `π ^ (r*2)` instead.
`π * (r^2)` is what I meant in my previous answer when I described it without using the symbols as PI times (R squared).
