Answer 2

Answer:

Step-by-step explanation:

∴Radius⇒7 cm

  Height⇒14 cm

∴WE know that for find the of the  right circular cylinder

    ∴ curved surface area⇒2πrh                   (π=22/7)

                                           ⇒2×22/7×7×14

                                            ⇒2×22×14

                                              ⇒44×14

                                                 ⇒616 cm²

     ∴ total surface area​⇒2πrh +2πr²

                 ⇒2×22/7×7×14+2×22/7×7×7

                  ⇒2×22×14+2×22×7

                    ⇒44×14+44×7

                     ⇒616 cm² +308 cm²

                     ⇒924 cm²
