Answer 2

Diameter = d = 35mm

Radius of the circle =r=

Circumference of brooch = 2πr

                                        = 2*22/7*35/2

                                        = 110mm

Length of wire required = 110 + 5 x 35

                                      = 110 + 175

                                      = 285mm
