Question

4. Sofia is buying lace to sew around the edge of a round tablecloth. The radius of the tablecloth is 24 feet. If lace is sold by the yard, what's the smallest number of whole yards she can buy to have enough lace for the tablecloth?​

Answer 1

• 51 yards

===========

Find the circumference of the table:

• C = 2πr
• C = 2*3.14*24 ft = 150.72 ft

Convert the length into yards, considering 1 yd = 3 ft:

• 1 foot = 1/3 yd

• 150.72 ft =
• 150.72/3 yd =
• 50.24 yd

Sofia needs to buy 51 yards of lace as it is the smallest whole number greater than 50.24.
