Final answer:
The circumference of the bicycle's tires, which are 52 cm in diameter, is approximately 163.36 cm. This is calculated using the formula C = πd, where C is the circumference and d is the diameter.
Step-by-step explanation:
To calculate the circumference of the bicycle's tires, we can use the formula C = πd, where C is the circumference and d is the diameter of the tires. The diameter given is 52 cm, so the circumference C = π × 52 cm. Therefore, the circumference of each bicycle tire is approximately 163.36 cm.
The 3.5 km distance traveled does not directly factor into calculating the circumference; however, it can be used in conjunction with the circumference to determine how many times the tire rotated during the trip. This is calculated by dividing the total distance traveled by the circumference of one tire.
For example, a bicycle traveling 3.5 km (or 350,000 cm) with tires of circumference 163.36 cm would make approximately 2141.65 revolutions.
