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.
It is given in the question that,
Diameter of table cover = 1.5 m
∴ Radius of circular cover = 1.5/2
We know that,
Circumference of the circle = 2πr
∴ Circumference = 2 × 3.14 × 
= 3.14 × 1.5
= 4.71 m
Also, it is given in the question that:
Cost of 1 m of lace = Rs 15
∴ Cost of 4.71 m of lace = 4.71 × 15
= Rs 70.65
