An insect subtends an angle of only 3.4 x 10-3 rad at the unaided eye when placed at the near point. What is the angular size (magnitude only) when the insect is viewed through a microscope whose angular magnification has a magnitude of 110?

Magnification M = B / alpha
Angle subtended by the image at eye, B = M (alpha)
B = 110 * 3.14/1000
B = 0.374 radians
