When a patient is being fitted with contact lenses, thecurvature of the patient's cornea is measured with an instrumentknown as a keratometer. A lighted object is held near the eye, andthe keratometer measures the magnification of the image formed byreflection from the front of the cornea. If an object is held11.0 cm in front of a patient's eye,and the ratio of the height of the reflected image to that of theobject is 0.027, what is the radius of curvature of the patient's cornea?
