Question

a point travels halfway around a wheel with a radius of 1 foot. to the nearest foot, how many feet does it travel? feet

Explanation:

Step1: Recall circumference formula

The circumference of a circle is $C = 2\pi r$, where $r$ is the radius.

Step2: Calculate half the circumference

Since the point travels halfway, we use $\frac{1}{2}C = \pi r$. Substitute $r=1$ foot:
$\frac{1}{2}C = \pi \times 1 = \pi$

Step3: Approximate to nearest foot

$\pi \approx 3.14$, which rounds to 3.

Answer:

3
