Asked by Bob

George plans to cover his circular pool for the upcoming winter season. The pool has a diameter of 20 feet and 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?
Answered by Steve
as you recall
a = πr^2
c = 2πr

so, the pool with cover has a diameter of 21 ft. The radius is thus 10.5

Now just plug and chug.
