mylen [45]

Answer:

3.8m

Step-by-step explanation:

Since Lara is putting lace trim around the border of a circular tablecloth, by the time she finishes she has covered the circumference.

$C=\pi \: d$

where d is the diameter of the circle.

It was given that the diameter of the circular table cloth is 1.2 meters.

$C=3.14 \times 1.2$

$C=3.768$

Therefore the length of the lace she needed is 3.8m
