Answer:
After about 340 seconds the cooler should be 40% full
(x - h)^2 + (y -k)^2 = r^2
(h,k) is the center and r is the radius.
(x + 2)^2 + (y + 8)^2 = 16
It was the temperature peak 89.4 without this there would be no difference.
For a right triangle with legs legnth a and b and hyptonuse c
a^2+b^2=c^2
9 feet from base, that's one leg
wire is hypotnuse, it's 1 more than height on tree
c=b+1
so
9^2+b^2=(b+1)^2
81+b^2=b^2+2b+1
minus b^2+1 from both sides
80=2b
divide both sides by 2
40=b
c=b+1
c=40+1
c=41
legnth of wire is 41ft
