Answer: 3 ft 8 in
Explanation:
The sum of their wingspan is the circumference of the tree.
Use the formula: C = πd to find the diameter (d) of the tree.
5'6" + 6' = 11'6" = 11.5 ft
11.5 ft = πd → 11.5/π = d → 3.66 ft = d
Next, convert the decimal (feet) into inches

which means the decimal of .66 ft rounds to 8 in
⇒ d = 3 feet 8 inches (3' 8")
