Answer:
12π OR 37.699
I'm not sure if your teacher wants your answer to be in decimal form or not
Step-by-step explanation:
The formula for the circumference of a circle is: 2πr
Before we begin this problem, it's important to know that diameter is the radius x2 (2r=d) OR the radius is half of the diameter
Because we know the diameter and we need the radius, let's divide 12 by 2 --> we get 6 for our radius
Now plugging in:
2π(6) or 12π
answer:
12π OR 37.699
