Final answer:
To determine the minimum amount of fencing needed to enclose Cody's circular track, we calculate the circumference using the formula C = πd, where the diameter d is 8.5 meters. Multiplying 8.5 meters by π (approximately 3.14), we find that at least 26.69 meters of fencing is needed.
Step-by-step explanation:
The student's question involves calculating the amount of fencing needed to enclose a circular track.
Given that the diameter of the track is 8.5 meters, we can use the formula for the circumference of a circle, which is C = πd, where C is the circumference and d is the diameter.
Since the diameter is given as 8.5 meters, we can plug this value into the formula to find the least amount of fencing needed.
Using the formula, we get: C = π × 8.5 meters.
Assuming the value of π to be approximately 3.14, the calculation would lead to C = 3.14 × 8.5 meters = 26.69 meters.
Therefore, Cody would need at least 26.69 meters of fencing to enclose the track completely.
