2.8 mm
Explanation:
given,
diameter of field at 40x is equal to 5.6
diameter of field at 80 x = ?
Field of view is the circle you see when you look through the ocular lens of the microscope.
when you use 80 X
then the diameter of the field of view becomes =

= 2.8 mm
so, when we use 80 X the diameter becomes half of 40 X
