Introduction

In mathematics, calculating distances around circular objects is a fundamental concept that has numerous real-world applications. In this article, we will explore how to calculate the distance traveled by a race car around a circular racetrack. We will use the given information to determine the correct answer and provide a step-by-step solution.

Understanding the Problem

The problem states that a circular racetrack has a radius of $2,016$ feet. A race car starts at point $B$ and travels counterclockwise around the track to point $C$ . The question asks how many feet the race car traveled.

Calculating Distance Around a Circle

To calculate the distance traveled by the race car, we need to use the formula for the circumference of a circle. The formula is given by:

Circumference = 2πr

where $r$ is the radius of the circle and $\pi$ is a mathematical constant approximately equal to $3.14$ .

Applying the Formula

In this case, the radius of the circular racetrack is $2,016$ feet. We can plug this value into the formula to calculate the circumference:

Circumference = 2π(2,016)

Circumference = 2(3.14)(2,016)

Circumference = 12,672.32

Therefore, the distance traveled by the race car is approximately $12,672.32$ feet.

Conclusion

In conclusion, we have calculated the distance traveled by a race car around a circular racetrack with a radius of $2,016$ feet. We used the formula for the circumference of a circle to determine the correct answer. The distance traveled by the race car is approximately $12,672.32$ feet.

Additional Information

It's worth noting that the answer choices provided in the problem are $2,456$ feet, which is significantly less than the calculated distance. This suggests that the answer choices may be incorrect or incomplete.
