Optics Problem

  1. Does anyone know how to solve this problem? I tried using the spherical interface formula (n1/p)+(n2/q)=((n2-n2)/R) and I get q=15cm which I cannot seem to relate to the answer provided (23cm). Anyone know the correct way to approach this problem?

    You probably need to account for the flat end of the rod as well.
