Answer:

7.68 radians

Step-by-step explanation:

The arc length formula is s = rФ, where Ф is the central angle.

                                                                  s

Solving this formula for Ф, we get Ф = -------

                                                                   r

                                                                                      43.98π

and in this particular case, the central angle is Ф = -------------- , or

                                                                                         18

approximately 7.68 radians.
