Answer 1

Answer: Length of lace required is 4.71m and its cost will be 70.65 rs.

Step-by-step explanation: As diameter is 1.5m , radius will be 0.75

Now as we are covering the adge of circular table with lace , the length of lace required will be its circumference .

Circumference = 2πr = 2×3.14×0.75 = 4.71 m

Now Cost of Lace = 4.71 × 15 = 70.65
