    Answer:

    The magnification is  m = -2.15

    Explanation:

    From the question we are told that

       The  radius is  r = 14.0 \ m

        The  focal length eyepiece is  f_e = 3.25 \ m

    Generally the objective focal length is mathematically represented as

            f_o = \frac{r}{2}

    =>     f_o = \frac{14}{2}

    =>     f_o = 7 \ m

    The  magnification is mathematically represented as

          m = - \frac{f_o }{f_e }

    =>    m = - \frac{7 }{ 3.25 }

    =>   m = -2.15
