Question

Lara is putting lace trim around the border of a circular tablecloth. The tablecloth has a diameter of 1.2 meters. What is the length of the lace she needs? Round to the nearest tenth of a meter.

Answer 1

3.8m

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:

`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 * 1.2`

`C=3.768`

Therefore the length of the lace she needed is 3.8m
