Sally is making a tablecloth and wants to put lace around the edges. How much lace will she need to purchase if the radius is 1.5 ft.
Circumference = pi * diameter
C = 3.14 * 3
C = 9.42 feet
Since most lace is sold by the yard, she should buy at least 3 1/4 yards.
To find out how much lace Sally will need to purchase, we first need to calculate the circumference of the tablecloth. The circumference is the distance around a circle and can be found using the formula: circumference = 2 * π * radius.
Given that the radius is 1.5 ft, we can substitute this value into the formula:
circumference = 2 * 3.14 * 1.5
= 9.42 ft
So, Sally will need to purchase approximately 9.42 feet of lace to go around the edges of the tablecloth.
