Q.6 Saima wants to put a lace on the edge of a circular table cover of diameter 1.5 m. Find the length of the lace required and also find its cost if one metre of the lace costs Rs.15. (Take $$\pi$$= 3.14)
$$\therefore$$Radius$$=\frac{1.5}{2}= 0.75 m$$
$$\therefore$$Length of the lace $$= 2\pi r = 2 × 3.14 × 0.75 = 4.71 m$$
