Does anyone know??????

Answer:
58.4
Step-by-step explanation:
To find the circumference of a circle, multiply the diameter by pi.
[tex]circumference=\pi d[/tex]
In this case, the diameter is 18.6, and 3.14 is the substitute for pi.
[tex]18.6*3.14=58.404[/tex]
[tex]58.404[/tex] ≈ [tex]58.4[/tex] (nearest tenth).
