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:
![C=\pi \: d](https://tex.z-dn.net/?f=C%3D%5Cpi%20%5C%3A%20d)
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](https://tex.z-dn.net/?f=C%3D3.14%20%5Ctimes%201.2)
![C=3.768](https://tex.z-dn.net/?f=C%3D3.768)
Therefore the length of the lace she needed is 3.8m
.7
because you need to get the original unit price which is 0.7 then multiply that by 1 and get your answer

Answer:
9
Step-by-step explanation:
if z=8 then z^2 would be 64, which is not equal to 80
iz z=9 then z^2 would be 81, which is closer to 80 than 64
therefore, 9 is the whole number than z would be closest to
