Answer:

  -15

Step-by-step explanation:

weqwewe [10]
Let the volume of the cylinder be V cubic meters, the diameter be d meters and the height be h meters.
Now we can write the formula for the volume as follows:
V=\pi\frac{d^{2}}{4}h
Rearranging the formula, the height becomes:
\large h=\frac{4V}{\pi d^{2}}

What is the difference between the smallest 6-digit whole number and the greatest four digit whole number
kupik [55]
First, lets start with the greatest 4-digit number. That would be 9,999.99999999999, with 9 to ∞, because the next number is a 5-digit number. The smallest 6-digit number is 100,000, because the number preceding 100,000 is a 4 digit number. To find difference, you have to subtract. 100,000 minus 9,999.9999 continued gives you 90,000.000000 to ∞ with a one with 1 at the end. You would write 90,000.01 with bar notation over only the 0 to indicate that it goes on to infinity.

Expand and simplify <br> (V5-V2)(V2+V5)
gizmo_the_mogwai [7]

Answer:

3

Step-by-step explanation:

(\sqrt{5} - \sqrt{2})(\sqrt{2} + \sqrt{5})\\\sqrt{5} (\sqrt{2} + \sqrt{5}) - \sqrt{2} (\sqrt{2} + \sqrt{5})\\\sqrt{5} * \sqrt{2} + \sqrt{5} * \sqrt{5} - \sqrt{2} * \sqrt{2} +\sqrt{2} * \sqrt{5}\\ \sqrt{5*2} + \sqrt{5*5} - \sqrt{2*2} - \sqrt{2*5}\\\sqrt{10} + \sqrt{25} - \sqrt{4}  - \sqrt{10}

plus root 10 and minus root 10 gets cancel . So,

\sqrt{25} - \sqrt{4} \\\sqrt{5^{2} } - \sqrt{2^{2} }

square and root gets cancel

5 - 2
