Answer 2

Answer:

lateral surface area of a cylinder = 2πrh

                                =2·π·7·9                              (putting the value of pie =3.14)

                               ≈395.84067cm²

total surface area of a cylinder =2πrh+2πr2

                                                  =2·π·7·9+2·π·72  (putting the value of pie=3.14)

                                                  ≈703.71675cm²
