Answer:
Below.
Step-by-step explanation:
There are 2 similar triangles here.
The large one made from the tree, the trees's shadow and the line from top of the tree to the and of the shadow The other one is the small triangle inside the large one , made from emily , emily's shadow and line from top of emily's head to the end of the shadow.
Corresponding sides in these 2 triangles are in the same ratio, so if h is the height of the tree, then
h / emil's height = length of tree's shadow / length of emily's shadow
h / 6 = 18/5
5h = 6*18
5h = 108
h = 108/5
= 21.6.
The scale factor for emily's to the object = 5/18.
Hope this helps! ask if you have questions about it :)
Answer:
22,000 miles
Step-by-step explanation:
Circumference of a circle: 2πr (r is the radius)
Substitute the length of the radius given, which is 3500. Also, substitute the approximate value of π, which is 3.14.
Circumference = 2 * 3.14 * 3500
Circumference = 21980
This rounds to about 22,000, so the answer is 22,000 miles.
I hope this helps! Feel free to ask any questions!
