Final answer:

The length of the circumference of an 18-inch circle is approximately 56.52 inches.

Step-by-step explanation:

The length of the circumference of a circle can be found using the formula C = 2πr, where C is the circumference and r is the radius of the circle.

In this case, the radius of the circle is 18 inches. Thus, the length of the circumference is:

C = 2π(18) = 36π inches.

Since we want the length of the circumference in inches, we can use the approximation π ≈ 3.14. Therefore, the length of the circumference is approximately:

C ≈ 36 × 3.14 = 113.04 inches.

Therefore, the correct answer is D) 56.52 inches.
