Answer:

5.732484076 =d

Step-by-step explanation:

The circumference is given by

C = pi*d

18 = 3.14 *d

Divide each side by 3.14

18/3.14 = 3.14d/3.14

5.732484076 =d

Answer: d ≈ 5.73 ft

Step-by-step explanation: Using the formulas

                                             C=2πr

                                             d=2r

                                             Solving for d

                                             d= C/π = 18/π ≈ 5.72958ft
