The area of a circle is pi (for which you would probably use 3.14) time the radius squared.

So, using that, what is the answer?

the area of the path is the total area minus just the pool. Since the path is 2m wide, the radius of the whole is 22m. So the area of just the path is

π(22^2-20^2) = 84π m^2
