Here's how to solve this problem:**1. Convert units:*** The length of the rope is given in meters (9.68 m), but the radius of the tree trunk is given in centimeters (14 cm). We need to use consistent units. Let's convert the radius to meters: 14 cm = 0.14 m**2. Calculate the circumference of the tree trunk:*** The circumference (C) of a circle is given by the formula C = 2πr, where 'r' is the radius.* C = 2 * π * 0.14 m ≈ 0.88 m**3. Calculate the number of turns:*** The number of turns is simply the total length of the rope divided by the circumference of the tree trunk.* Number of turns = 9.68 m / 0.88 m ≈ 11**Therefore, the answer is 11.**
