Question

an electric toy train travels around a christmas tree in a circle. the train track measures 6 feet in diameter. what is the distance that the train travels?

Explanation:

Step1: Recall circle circumference formula

The distance the train travels is the circumference of the circular track, given by $C = \pi d$, where $d$ is the diameter.

Step2: Substitute diameter value

Substitute $d = 6$ feet into the formula:
$C = \pi \times 6 = 6\pi$
If using $\pi \approx 3.14$, $C \approx 6 \times 3.14 = 18.84$

Answer:

The train travels $6\pi$ feet (or approximately 18.84 feet)
