Answer:
meters
Step-by-step explanation:
Let's take climbing down as "negative" and climbing up as "positive". Now, we can simply use the numbers and signs to find the change in elevation.
meters down means 
meters up means 
So, now we have: 
<u>Eric's elevation changed 
meters above. So after the 2 moves, he is up by meters.</u>
The formula is : V = pi r^2H
R = 5
h = 8
v = ?
Find the volume
v = pi r^2H
v = 3,14 *(5)^2 * 8
v = 3,14 * 25 * 8
v = 2800 cm^3
The Pythagorean theorem can be used to find the straight-line distance between the starting point and an ending point that is 4.5 km south and 12.0 km east of there.
d² = 4.5² + 12.0² = 20.25 + 144.0 = 164.25
d = √164.25 ≈ 12.816 . . . km
