Calculating area?

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 {
    set radius(radius) {
      this.area = Math.pow(3.14, radius * 2)
      this.circumference = 2 * 3.14 * radius ;
      this._radius = radius
    }


}

const circ = new Circle();

The instructions say the formula for area is area = Ī€*r^2, which assumes that you know to apply the exponent first. Perhaps they should have written it as: Ī€ * (r^2). What the code above is doing is actually Ī€ ^ (r*2) instead.

Ī€ * (r^2) is what I meant in my previous answer when I described it without using the symbols as PI times (R squared).
