Answer 1

total sheet required for this=TOTAL SURFACE AREA OF VESSEL

                                     =2πR[R+H]

                                    = 2*22/7*14[14+16]

                                     =88*30

                                      =2640 CM ²

VOLUME=πR²H

             =22/7*14*14*16

             =9856 CM ³

Answer 2

Answer:

2640 cm², 9856 cm³

Step-by-step explanation:

Given, radius = 14 cm and height = 16 cm.

∴ Area of sheet required = Total surface area.

                                         = 2πr(r + h)

                                         = 2 * 22/7 * 14(14 + 16)

                                         = 2 * 2 * 22(30)

                                         = 2640 cm².

∴ Capacity of the vessel = πr²h

                                        = (22/7) * (14)² * 16

                                        = 9856 cm³.

Hope it helps!
