Final answer:
The rider travels approximately 471.24 meters in 3 complete rotations around the Ferris wheel.
Step-by-step explanation:
To calculate the distance traveled by a rider on a Ferris wheel, we need to find the circumference of the wheel. The circumference is calculated using the formula: C = π * d, where C is the circumference and d is the diameter of the wheel. In this case, the diameter is 50 meters, so the circumference is C = π * 50 = 50π meters. Since the rider travels the circumference for each rotation, we can multiply the circumference by the number of rotations to find the total distance traveled. In this case, the rider travels 3 complete rotations, so the total distance traveled is 3 * 50π = 150π meters, or approximately 471.24 meters.
