$C=32\pi{m}$

There is a formula for finding the circumference of a circle. It is:

Let C= circumference of circle

Let r= radius of circle
 

$C=2\pi{r}$

Now that we know this formula, let's plug in the information that we know and simplify from there:

$C=2\pi{(16)}=32\pi{m}$

The directions are to leave the answer in terms so pi,so there is no need to provide a decimal approximation. And of course, include units in your final answer
