Answer 2

Answer:

Step-by-step explanation:

Surface area of a sphere = 4 x π x r²

                                           = 4 x 3.14 x 4 x 4

                                           = 200.96 or 201 approx

Volume of a sphere = $\frac{4}{3}$ x π x r³

                                  = $\frac{4}{3}$ x 3.14 x 4 x 4 x 4

                                  = 267.9466666666666666..........³
