I think its D. warning I might be wrong lol
20mi
H^2 = 12^2 + 16^2
H^2 = 144 + 256
H^2 = 400
H = square root of 400 = 20
Answer:
13.35 millimeter. (About)
Step-by-step explanation:
To find the area or circumference of any circle, you need to use pi. So, if we are trying to fine the area of a <em>semicircle, </em>you use the the formula:
πr²/2
So, if the radius is 8.5,
8.5 · 3.14 = 26.69
Now we divide it by 2.
26.69 = 13.345
Since the question is asking to round to the hundredths, the answer will be 13.35 millimeters.
Start at 60
hike down 137 below so new is 60-137=-77m
then go down again 57
-77-57=-134
new altitude is -134m
