Answer:
its without a q at the end
Explanation:
All the options are correct.
If we look at the formula of prismoidal, we can see that it contains, three areas = area of faces at top and bottom and area of midway section
Thus it can be used to calculate the a) calculate surface area for cylindrical rings And b) estimate the surface area of edged non-prismoidal solids.
In the volume formula of prismoidal, the factor (depth/6) is multiplied by the three areas as mentioned above, this gives the volume of faces at top and bottom and midway section. Thus option C and D are also correct.
Answer:
Explanation:
No actual diagram has been provided and none can be found online representing this question. Regardless, Rivers will always from based on elevation from the highest point to the lowest point due to gravity. That being said the vast majority of rivers on average have been found to flow east to west. This does not mean all rivers and varies on the elevation like mentioned before, the Amazon river instead flows west to east.
Plain - flat or Rolling Land with few changes in elevation
