Reflecting globe in a garden

Reference no: EM13547026

A person 1.6 m tall stands 2.9 m from a reflecting globe in a garden. (a) If the diameter of the globe is 33 cm, where is the image of the person, relative to the surface of the globe? (Enter a negative value if the image forms behind the globe.) I tried -8.26 and -8.33 as the answers but the homework keeps telling me it's wrong (b) How large is the person's image? cm
