Answer:
the answer is 14 feet
Explanation:
The tree's root is 9 feet below ground so that means that we have to subtract 23 (which is the total length of the tree) to 9 (which is the 9 feet which is the length of the tree's root underground) so your answer would be 14 feet of elevation above ground. (the radius has nothing to do with the height or elevation of the tree).
