Answer:

1.9 mm

Step-by-step explanation:

Circumference of circle = 2πr

             2πr = 12.1 mm

     [tex]\sf 2* \dfrac{22}{7}*r= 12.1\\\\[/tex]

                  [tex]\sf r = \dfrac{12.1*7}{2*22}\\\\[/tex]

                     = 1.925

                 [tex]\sf \boxed{radius =1.9 \ mm }[/tex]
