Answer:


Step-by-step explanation:radius of cone and hemisphere is 3.5cm(given)

height of cone= full height of toy-radius of hemisphere

                         =15.5-3.5=12cm


total surface area of toy=C.S.A of cone+C.S.A of hemisphere

                                        =\pirl+2\pir^2

                                               =22/7 *3.5*12.5+22/7*2*3.5*3.5

                                                       =214.5cm^2                                                  

l=                                                                                                                          \sqrt{h^2+r^2}

=\sqrt{12^2+(3.5)^2}

=sqrt(156.25)

=12.5 cm
