Answer:2√12 π
Step-by-step explanation:
The formula for area of circle = r^2 π
Since the question tells us that the area of the circle is 12π, we can make r^2 π = 12π, so r^2 = 12 when we cancel π from both sides. Then, r = √12.
The formula for circumference of circle = 2πr
We can now plug in √12 for r and we'll get 2√12 π.
