Answer:
18.85
Step-by-step explanation:
the formula to finding the circumference of a circle is
2πr
the picture shows that you have the diameter, so lets take half of it :)
2π3
when this is plugged into the calculator, it comes out to be
18.85
you should round up to the tenth place by making it 18.9 ... however i think your teacher messed it up.
but that's alright, just put the answer as A, because i think that is what your teacher intended to be correct.
I hope this helped!!
stay safe!!
