1.4 decameters. Hope this helped!
A) add the two elevations together:
6900 + 8100 = 15,000 meters.
B) Divide the total distance by 2:
15,000 / 2 = 7,500 meters.
Because the distance to the halfway point is larger than the elevation of Ojos del Salado, the elevation would be below seal level.
C Add the halfway point from part B to the lowest elevation:
-8100 + 7500 = -600 meters
In polar coordinates, we have
From this we can write
If
, then
, so we get
Answer:
to guarantee that both formulas are the same.
Step-by-step explanation:
Dimensionally speaking, the volume is the cube of length. By direct comparison, we find that 
have length units, whereas 
have area unit, that is, the square of length.
Hence, to guarantee that both formulas are the same.
