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.
The circumference of a circle is calculated using:
[tex]C=\pi \: d[/tex]
where d is the diameter of the circle.
It was given that the diameter of the circular table cloth is 1.2 meters.
[tex]C=3.14 \times 1.2[/tex]
[tex]C=3.768[/tex]
Therefore the length of the lace she needed is 3.8m
