**Circumference of a 12 ft Circle**

**Introduction:** The circumference of a circle is directly proportional to its diameter. A 12 ft circle has a diameter of 12 ft. We'll utilize the formula for circumference to calculate its value.

**Key Aspects:**

**Radius:**The radius of a circle is the distance from its center to any point on its circumference. In this case, the radius is 6 ft (12 ft / 2).**Diameter:**The diameter of a circle is the distance across the circle through its center. In this case, the diameter is 12 ft.**π (Pi):**A mathematical constant approximately equal to 3.14159.

**Discussion:**

Using the formula Circumference = 2πr, we can calculate the circumference of a 12 ft circle:

**Circumference = 2 * π * 6 ft****Circumference = 12π ft****Circumference ≈ 37.699 ft**

Therefore, the circumference of a 12 ft circle is approximately 37.699 feet.
