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?

so use a basic formula here:

area of a circle = πr²

and the circumference of a circle = πd

a)

therefore the area of the pool cover is π multiplied by the radius² (which is the diameter of the pool cover plus the extra 12 inches divided by two, so the radius is 21/2 or 10.5) is 346.36(to two decimal places.)

b)

Using the same diameter, we can work out the length of the rope by multiplying the diameter (10.5) by π, which is 32.99 (to two decimal places).

the factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24. hope this ! mark brainliest! you v much! : )
