Question

the radius of a circle measures 3 mm. what is the circumference of the circle? use 3.14 for π, and do not round your answer. be sure to include the correct unit in your answer.

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the given values

Given $r = 3$ mm and $\pi=3.14$, we substitute into the formula: $C=2\times3.14\times3$.

Step3: Calculate the result

$C = 18.84$ mm.

Answer:

$18.84$ mm
