A brooch is made with silver wire in the form of a circle with a diameter of \(14 mm\). The wire is also used in making \(5\) diameters which divide the circle into \(10\) equal sectors as shown in Fig. (Use \(\pi=\frac{22}{7})\).
Estimate:
(i) The total length of the silver wire required is ________\(mm\)
(ii) The area of each sector of the brooch is _______\(mm^2\).
