Anna is covering a circular pool with a cover for winter. The pool's diameter is 24 feet. The cover extends 12 inches beyond the edge of the pool, and a rope runs along the edge of the cover to hold it in place. What is the area of the cover? What is the length of the rope.

I know how to find area of a circle (formula is A=pi times the radius squared) but I don't know how to find the diameter of of the cover because 12 inches are added. Also, I am kinda lost on how to find the length of the rope because I'd have to find the diameter of the cover first I think. P.S. Radius is half the diameter.
Thanks for your help
