Question

the circumference of a circle is $2\pi$ m. find its radius, in meters.

Explanation:

Step1: Recall circumference formula

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

Step2: Substitute given circumference

Substitute $C = 2\pi$ into the formula:
$2\pi = 2\pi r$

Step3: Solve for radius $r$

Divide both sides by $2\pi$:
$\frac{2\pi}{2\pi} = r$
