Answer:

12π or 37.7 cm

Explanation:

The formula for the circumference of a circle is 2πr or πd. In this case, r represents the radius, a segment from the center of the circle to any point on the circle. The d stands for diameter, a line running through two endpoints on the circle with the center point in the middle. This means that the diameter is twice the radius (imagine a line cutting across half a pizza and then a line cutting across only a quarter, this is diameter and radius at work!).

To solve for the circumference, I will use both formulas (although πd is easier since the diameter is already given)

2πr

2π(12/2)

2π(6)

12π ≈ 37.7 cm

πd

π(12)

12π ≈ 37.7 cm
