Hemisphere is acting like a plano-convex lens, its focal length can be obtained from lens makers formula as, (1/f) = (2-1) (1/R)
 
Hence focal length f = R
 
q.32 :- virtual image will be formed when object distance is less than focal length.
             Hence if object distanceis R/2 , we get virtual image
 
q.33 :- if object distance is 2R, i.e. twice of focal length, we get image at distance  2R on other side.
            Nature of image is real, inverted and same size
 
q.34:- if lightray making grazing incidence (i=90°) at spherical surfae , then light ray is acting as tangent to hemisphere,
            Such a light ray will not pass through hemisphere
