A circular park of 20m diameter has a circular path just inside the boundary with a width of 1m.The are of the path is
15pi
17pi
19pi
25pi
I caught my error...It had a 20 m diameter...
so the area of the park would be
The area of the park enclosed by the path would be
So then we see that the difference between the two will give us the area of the path.
Does this make sense? Sorry about that; it was a mistake on my part...misread the problem.
