Question

lana is putting a lace trim arount the border of a circular tablecloth. the tablecloth has a diameter of 1.2 meters. to the nearest meter. what is the least ammount of lace she needs?

Answer 1

Answer:

4m

Step-by-step explanation:

We are looking for the circumference

We need to find the radius

r = d/2 = 1.2/2 = .6

C = 2*pi*r

C = 2*pi*(.6)

C = 1.2*pi

We can approximate pi by 3.14

C =1.2*3.14

C =3.768 m

To the nearest meter

C = 4m
