Explanation:
The formula for circumference is
, where r = radius. We are using 3.14 instead of pi here.
The radius is shown to be 2.5 cm, simply plug that into the equation and solve.
To solve, you must first carry out
.
Then, multiply that product by pi, or, in this case, 3.14:

So, the answer exactly is 15.7. When rounded, it's technically 15.70 but that is absolutely no different than the exact answer.
