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 meter of the lace costs ₹15. (Take π = 3.14)

Given that, The diameter of circular table cover = 1.5 m

The cost of 1 m of the lace = ₹ 15

Radius of circular table cover = 1.5/2 m = 0.75 m

Thus, 

Circumference of circular table cover = 2$\mathrm{\pi }$r

= 2 $\times$ 3.14 $\times$ 0.75

= 4.71 m

Therefore, The length of required lace = 4.71 m

We get, Cost of 4.71 m lace = 4.71 $\times$ 15

= ₹ 70.65
