The circumference of a circle is given by the formula C = πd, where C is the circumference, π is the mathematical constant pi (approximately 3.14), and d is the diameter.
In this case, the diameter of the Ferris wheel is 80 meters, so its radius is half of that, or 40 meters. Therefore, the circumference of the Ferris wheel is:
C = πd = π × 80m = 251.2m (rounded to one decimal place)
Since the rider travels the full circumference of the Ferris wheel three times, the distance traveled is:
3 × C = 3 × 251.2m = 753.6m (rounded to one decimal place)
Therefore, a rider would travel approximately 753.6 meters in three complete rotations around the Ferris wheel.
