Answer:

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) Therefore, the length of the required lace is 4.71 m

plss mark me as brilliant

Answer 2

Let's take π as 3.14

circumference =πd=1.5π m

length of lace required = circumference of the circle

= 1.5×3.14 = 4.71 m

length of lace required = 4.71 m

one meter of lace = Rs.15

4.71 m lace = Rs. 4.71×15

                   = Rs.70.65

4.71 m of lace is required, which will cost Rs. 70.65
