Answer:

Step-by-step explanation:

  Let,

            L.S.A of 1st cylinder be 2πRh  

            L.S.A of 2nd cylinder be 2πrh

                                           ( Ratios are not equal so,we should take 2 radius)

             Then, ratio = 2πRh : 2πrh

                                   2πRh

                                    2πrh

                       

                        =  2πh(R)

                            2πh(r)

                       = R

                          r

     Ratio = R : r
