It's showing that image distance is incorrect. Can you please help?

An object 1.30 cm high is held 3.00 cm from a person's cornea, and its reflected image is measured to be 0.167 cm high. What is the magnification? magnification: 0.13 Where is the image? 0.39 image distance: cm Enter numeric value Incorrect Find the magnitude of the radius of curvature of the convex mirror formed by the cornea. magnitude of radius of curvature: 0.9 cm Note: This technique is used by optometrists to measure the curvature of the cornea for contact lens fitting. The instrument used is called a keratometer, or curve measurer.A 6.61 mm high rey sits on the axis of, and 13.7 cm in front of, the thin lens A, whose focal length is 6.23 cm. Behind lens A there is another thin lens, lens B, with a focal length of 26.5 cm. The two lenses share a common axis and are 58.1 cm apart. Is the image of the rey that lens B forms real or virtual? How far from lens B is this image located? Express the answer as a positive number. image distance from lens B: 61.3 cm What is the height of this image? Express the answer as a positive number. 10.41 image height: mm Incorrect
