Answer:
1072.3
Step-by-step explanation:
A hemisphere is half of a sphere, so the volume V of the hemisphere is the volume of the sphere divided by 2.
V = (2/3)*
= (2/3)*
= (2/3)**512
= 1072.3
Answer:
Fertilizer puts nitrogen into the soil, so using fertilizer puts more nitrogen into the carbon cycle.
When you use fertilizer, its because a certain plant you are planting uses all the nitrogen in the soil, so it won't grow next time. Too much fertilizer, though, would burn up your plant (not literally). Some plants put their own nitrogen into the soil. I can't think of one off the top of my head, but I believe potatoes do. Anyways, this is where crop rotation came into play.
Things like corn take a lot of nitrogen, so the next time you had to plant whatever plant potatoes, which again may be wrong, in order to get nitrogen for the corn to grow next season. Today we have fertilizer, so we can give them nitrogen while they grow, instead of putting in other plants, taking more time.
So really, it doesn't do much, because your plant takes all the nitrogen that the Fertilizer adds.

<u>a.√ 38 = </u><u></u>
<u>b. √ 79 = </u><u></u>
<u>Step-by-step explanation:</u>
Here we have , to find Approximate value of each expression shown.
We know that , A square root of a number is a value that, when multiplied by itself, gives the number. Example: 4 × 4 = 16, so a square root of 16 is 4. Note that (−4) × (−4) = 16 too, so −4 is also a square root of 16.
The symbol is √ which always means the positive square root. Example: √36 = 6 (because 6 x 6 = 36)
<u>a.√ 38
</u>
We know that value of √36 = 6 , and here we have √ 38 which value will be slightly greater then 6 Let's find out:

<u>b. √ 79</u>
We know that value of √81 = 9 , and here we have √ 79 which value will be slightly less then 9 Let's find out:
