George plans to cover his circular pool for the upcoming winter season. The pool has a diameter of 20 feet and the cover extends 12 inches beyond the edge of the pool. A rope runs along the edge of the cover to secure it in place.

a.
What is the area of the pool cover?
b. What is the length of the rope?
It's two questions that it's asking for. It's an open ended on circumference and area.

The pool has a radius of 20/2 = 10 feet

The cover has a radius of 10 + 1 = 11 feet

Area of the cover = πr^2 = 121 π sq ft

Circumference of the cover = 2πr = 22 π ft

I'm sorry elijah I need your help
