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)​

Answer 1

Answer:

length of lace = 4.71 m

cost of lace = 70.65 rs

Explanation:

diameter = 1.5 m

radius = 1.5/2 = 0.75 m

circumference of the circle = length of the lace

= 2× 3.14 × 0.75 m

= 4.71 m

Cost of lace = 4.71 ×15

= 70.65 rs
