104.9

Step-by-step explanation:

To find the circumference of a circle, we need to use the formula which is

C = 2*π*r

Rewrite with radius

C = 2*π*16.7

Solve

C = 2*π*16.7 = 104.876

Now we have to round. Remember, if it is 4 or below round down and if it is 5 or above, round up.

104.876 - 6 is more than 5

104.88 - 8 is more than 5

104.9 is the final answer
