Question

4. Find the total surface area of a right circular cylinder whose radius is equal to 7.0 m and height is equal to
21.0 m.​

Answer 1

Step-by-step explanation:

surface area 2pir²h

=2x3.14x49x21

Answer 2

Answer:   1232 m^{2}

Step-by-step explanation:

T.S.A of right circular cylinder = 2 pie r(r + h)

                                                    = 2 (22/7) (7) (7 + 21)

                                                    = 2 (22/7) (7) (28)

                                                    = 2 (22) (7) (4)

                                                    = 44 (28)

                                                    = 1232 m^{2} (ANSWER)
