Circumference given the diameter = 3.14 × diameter

Diameter of larger mirror:

     37.68 cm = 3.14 d

     3.14d / 3.14 = 37.68 cm/3.14

     d = 12 cm.

Diameter of smaller mirror:
   
     d = 28.26 cm / 3.14
 
     d = 9 cm.

Subtract:

   12 cm - 9 cm = 3 cm

ANSWER:  The diameter of larger mirror is 3 cm greater than the smaller mirror.
