Question 1208412: A circular swimming pool, 25 feet in diameter, is enclosed by a deck that is 5 feet wide. What is the area of the deck? How much fence is required to enclose the deck?
Let me see. I understand this scenario to be one circle inside another circle. The circle inside is the pool, and the circle surrounding the pool is the deck.
To find the area of the deck, I must subtract the area of the pool from the area of the deck.
Yes?
To find how much fencing is required to enclose the deck, I must find the circumference of the deck.
Yes?

You can put this solution on YOUR website! .
This phrase from your post
"the circle surrounding the pool is the deck"
is incorrect.
A correct version is
"the ring surrounding the pool is the deck."
To answer first question, you should subtract the area of the smaller circle from the area of the greater circle.
Do you see the difference ?
To your second question, the answer is "Yes".

As I see from your post, you treat words ( terms ! ) very carelessly.
