Need help on this one....
Your town is building a circular ice rink with a diameter of 100 feet. Around the ice rink will be a walkway that is 10 feet wide. What is the approximate area of the walkway?
Thanks...

Just subtract the inner circle (the ice) from the whole area (including the walk)
pi(55^2  50^2)
