A brooch is made with silver wire in the form of a circle with diameter 35 mm. The wire is also used in making 5 diameters which divide the circle into 10 equal parts. Find the total length of the silver wire required.
284.9 mm
L- length of wire, P- perimeter of circle, D- diameter of circle L=P+5D=pi*D+5D=(pi+5)*D=8.14*35=284.9 mm
