a tree 20 feet tall with a circumference of 3 ft has a vine wound around 7 times. How long is the vine?
FinnZ [79.3K]

If the tree is 20 feet tall with circumference 3 feet then the length of  vince is around 21 feet.

Given the height of tree is 20 feet and the circumference of tree is 3 feet.

We have to find the length of vine.

Circumference is the perimeter of a circular object. Because the trunk of a tree is in shape of circle so the perimeter of the trunk is 2πr.

We have been given the circumference of tree be 3 feet.

Circumference=2πr

Because vine is 7 times the circumference so the length of vine being:

Length of vine=7*3

=21 feet.

Hence if the tree is 20 feet tall with circumference 3 feet then the vince is around 21 feet long.

I need help is it A B C or D
harina [27]
We evaluate b^2 - 4ac.  If the answer is positive, then there are two real solutions.  If it is zero, there is one real solution.  If it is negative, there are 2 complex solutions.  In this equation, a = 1, b = 5, c = 7.  Now we plug in the numbers.

5^{2}-4*1*7=1

Because this answer is positive, there are two real solutions.
