Answer:

Step-by-step explanation:

Firstly, Inner Curved Surface Area = 2πr(r+h)

                                                         = 2×22/7×3(3+56)

                                                         = 44/7×177

                                                         = 1112.57 cm²

Now, Outer Curved Surface Area = 2πr(r+h)

                                                        = 2×22/7×3.5(3.5+56)

                                                        = 2×22×29.75

                                                        = 119 cm²

Now, The Total Surface Area is = (1112.57+119) cm²

                                                     = 1231.57 cm²

Therefore, the Total Surface Area is 1231.57 cm²
