Answer:
6π
Step-by-step explanation:
You have to use the formula for the circumference of a circe:
Circumference = π(diameter)
However, you do not have the diameter, you have the radius.
Diameter = radius * 2
Diameter = 3 * 2
D = 6
Now you can substitute this value back into the Circumference formula:
C = πd
C = 6π
