Hello, please answer and explain :

You are building a robot and you need a lens for its eye. The focal length of the lens must be close to 15 cm. You order three acrylic lenses and have to decide which one has the right focal length. The manufacturer's specifications give you the radii of curvature shown in Table 1.
