If the area is 2289.06 whats the radius

I'm assuming you are referring to the radius of a square

The first thing we have to do is divide by pi, because it's the last thing you do when calculating the area.

2289.06/3.14

729

Now, we have to take the square root of this number because the radius in the area formula is squared.

729^1/2

27

So, the radius is 27.
