S.A. of 2 hemisphere = 4*22/7*r^2
                                  = 4*22/7*3.5*3.5
                                  = 154 cm^2
 .
CSA of cylinder = 2*22/7*r*h
                          = 2*22/7*3.5*10
                          = 220 cm^2

total S.A. of the article = 154 + 220
                                    = 374 cm^2  

purvisri02: thank you
