Question

Suppose the radius of a circle is three units what is the circumference

Answer 1

Answer:

$6\pi$ or $18.84$ units

Step-by-step explanation:

The circumference of a circle can be found using the formula $C=2\pi r$, where $C$ is the circle's circumference and $r$ is the circle's radius. We know that $r=3$ and that we are solving for $C$. Therefore:

$C=2\pi r\\C=2*\pi *3\\C=6\pi$

Since $\pi$ is approximately $3.14$, $6\pi =6*3.14=18.84$ units. Hope this helps!
