Suppose the number of leaves z on a tree varies directly with the height of the tree y in yards and directly with the cube of th
e hours x of direct sunlight that the tree receives. If a tree that is 7 yards tall and receives 6 hours of direct sunlight has 6048 leaves on it, then how many leaves will be on a tree that is 2 yards tall but receives 11 hours of sunlight?
21.98 is the circumference because is it 7 pi 7 times 3.14. For the area though it is 38.48 because you need to get the radius of the circle and you divided 7 by 2 which is 3.5 and here is the work A=πr2=π·3.52≈38.48451
