First, multiply the radius by 2 to get the diameter, 18 inches. Then, multiply the diameter by 3.14 (an approximation for π) to get a circumference of about 56.52 inches.
Convince Me!
If the diameter is doubled, the circumference doubles. Reason: C = π·d, so C is directly proportional to d. For example, d = 18 gives C ≈ 18·3.14 = 56.52; doubling d to 36 gives C ≈ 36·3.14 = 113.04, which is 2·56.52.
