The formula for the area of a circle is A = πr^2.
Given that the area is 16π, we can equate:
16π = πr^2
r^2 = 16
r = 4
Now, the circumference of a circle is found using the formula C = 2πr. Substituting the value of r:
C = 2π(4) = 8π ≈ 25.13 units
Therefore, the circumference of the circle is approximately 25.13 units.
