You can put this solution on YOUR website! What was the radius of the old one?

Also, is she gonna be watering the neighbors' grass now?
You can put this solution on YOUR website! Compared to the old system the circumference is 2pi (r+20)
2pi*r+40 and the old one was 2pi*r
So it is 40 meters larger than the old circumference.
