How far will the wheel travel in one complete turn?
It will travel the length of the perimeter of its wheel:
Then, we want to find the perimeter.
Since its diameter is 66 cm, then its radius is 33 cm (its half):
Since the perimeter is given by:
perimeter = 2πr
↓ since r = 33cm and π ≅ 3.14
perimeter = 2 · 3.14 · 33cm ≅ 207 cm
Answer: B
