What is the volume of a circular mine passage that is 19.0 feet in diameter and 210.0 feet long?

1 answer:

7 0

$d = diameter : d =19 \ ft \\ \\radius : r=\frac{d}{2}=\frac{19}{2}=9.5 \ ft \\\\ length of object : \ h=210 \ ft \\\\Circle Area : \ A= \pi r^2\\ \\Circular Volume = A*h = \pi r^2h \\ \\Circular Volume = \pi\cdot 9,5^2*210 =90,25 \cdot 210\cdot \pi =18952.5 \ \pi \ ft^3$

Geometric mean between 9 and 36

nlexa [21]

I've actually just learned this. We would set up the proportion as X/9=36/X so after we cross multiply we get x^2=324. Then we find the square root of both sides to simplify. And using my calculator the square root of x^2 is just x. And the square root of 324 is 18. So the final answer is x=18 or the geometric mean is 18.

KengaRu [80]

Answer:

B and D

Step-by-step explanation:

Take a look at all the options x=4, 3, 1, 2 > 0

So, we just care about the domain where x>0, which is $f(x)=x^{2}$ .

Then plug in x we will have the right answer.

The graph first represents the provided piecewise function option first is correct.

<h3>What is a piecewise function?</h3>

The graph of a piecewise function contains numerous curve components. It signifies that it has a plethora of definitions based on the value of the input. In other words, a piecewise function behaves differently depending on the input.

We have a piecewise function shown in the picture.

$\rm y=\left\{x\le-2:\sqrt{-x-2}\right\}$

$\rm y=\left\{-2 < x < 1:\dfrac{x}{x^{2}+x-2}\right\}$

$\rm y=\left\{x\ge1:\log_{2}\left(x+1\right)\right\}$

After plotting all the pieces of a function on the coordinate plane we will get a graph the same as shown in the first option.

Thus, the graph first represents the provided piecewise function option first is correct.
