Answer 2

Answer:

volume of sphere = 155232 cm cube and Surface area of sphere= 22176 cm sq

Step-by-step explanation:

Vol. of sphere = 4/3πr³

                        = 4/3×22/7×42×42×42

                        =88×42×42

                        =1764×88

                        =155232 cm³

surface area of sphere =4πr²

                                      =4×22/7×42×42

                                       =4×132×42

                                        =22176 cm²
