6 divided by 2 and 1 forths is going to be 8 out of 3
Answer:
Either A or C I think, Good luck!!!
Step-by-step explanation:
The formula for circumference is
![C=2 \pi r](https://tex.z-dn.net/?f=C%3D2%20%5Cpi%20r)
or
![C= \pi d](https://tex.z-dn.net/?f=C%3D%20%5Cpi%20d)
. We have a diameter for the semicircle, so let's use the diameter formula.
![C= \pi (1.7)](https://tex.z-dn.net/?f=C%3D%20%5Cpi%20%281.7%29)
which is either
![C=1.7 \pi](https://tex.z-dn.net/?f=C%3D1.7%20%5Cpi%20)
or C = 5.338 if we multiply pi in as 3.14. BUT this is only half a circle, so we only have half that distance around the outside. Therefore, the circumference of half this circle is 2.669 cm. But we need to add the 24 mm in. 24 mm in centimeters is 2.4 cm. So 2.669 + 2.4 = 5.069
Total 7*10^5 trees were planted.
Further explanation:
The product of both quantities will give us the total number of trees planted by the students for the community project.
So,
Given
![Trees\ planted\ by\ each\ student=2*10^2\\Total\ students\ in\ school=3.5*10^3\\Total\ trees\ planted= (2*10^2)*(3.5*10^3)\\= 7*10^5\ trees](https://tex.z-dn.net/?f=Trees%5C%20planted%5C%20by%5C%20each%5C%20student%3D2%2A10%5E2%5C%5CTotal%5C%20students%5C%20in%5C%20school%3D3.5%2A10%5E3%5C%5CTotal%5C%20trees%5C%20planted%3D%20%282%2A10%5E2%29%2A%283.5%2A10%5E3%29%5C%5C%3D%207%2A10%5E5%5C%20trees)
So, total 7*10^5 trees were planted.
