Math Word Problem, HELP!?
A homeowner needs to make a cover for a circular pool with a diameter of 18 feet. How much cover fabric should be ordered if the cover must extend 2 feet beyond the edge of the pool, and the rolls of material are 25 foot wide. Round out to the nearest square foot.
The formulas you will probably need are:
A=3.1416(r^2)
P=2(3.1416)(r)
Please provide the procedure and Thanks!

Since it needs to extend 2 feet beyond the edge, this means you need to add 2 to the radius, which is 9 (half of the diameter). So, use 11 as the radius to find the area: pi(11)^2 which equals 380.13 square feet of fabric needed.
I think the fact that the rolls of material are 25 feet wide is just excess information, though.
