What is the volume of the cynlinder?

vova2212 [387]

The volume of a cylinder can be found using the formula V=(pi)(r)^2(h)

V=(3.14)(8)^2(10)
V = 2010.62 Ft^3

I think that is the answer

Quadrilateral ABCD is inscribed in this circle.

Alecsey [184]

The sum of all interior angles in a polygon is

180(n-2), where n = sides, well, this is a QUADrilateral, so it has 4 sides, so the total is 360°.

now, let's find what angle C is first,

$\bf \stackrel{A}{(2x-40)}+\stackrel{B}{(116)}+C+\stackrel{D}{(x)}=360\implies C+3x+76=360
\\\\\\
C+3x=284\implies C=284-3x$

now, recall the "inscribed quadrilateral conjecture", where opposite angles are "supplementary angles", thus

$\bf \stackrel{\measuredangle A}{(2x-40)}+\stackrel{\measuredangle C}{(284-3x)}=180\implies -x+244=180
\\\\\\
64=x\\\\
-------------------------------\\\\
\measuredangle A=2(64)-40$

Can anyone help me in explaining subtraction of polynomials please help I’m desperate and I’m pretty much on my own when it come

Sidana [21]

Answer:

Think of combining like terms when subtracting polynomials. For example, 3x² and -2x². They both have x² in common. So, if you were to combine 3x² and -2x², it would be like 3x² + (-2x²). Think of this like 3 + (-2), which equals 1. In this case, it would equal 1x² or x².

Let's take this problem for example: 6x² - 3x + 4 - (-2x² +2x - 2)

Parentheses are super important; The first thing you want to do is distribute the negative sign out to everything inside the parentheses!

So,

6x² - 3x + 4 - (-2x² +2x - 2) *multiply the neg. to -2x², 2x, and -2

Now, if you do that, the equation would now look like:

6x² - 3x + 4 + 2x² - 2x + 2

Now think of combining like terms. Here are the like terms:

6x² - 3x + 4 + 2x² - 2x + 2 (Let's rewrite it to look like this...)

6x² + 2x² - 3x - 2x + 4 + 2

Let's combine the x²'s first, so... 6x² + 2x² = 8x²

Let's combine the x's, so... -3x - 2x = -5x

Let's combine the constants (numbers with no variable), so... 4 + 2 = 6

Your solution should be 8x² - 5x + 6

How to find the value of f(-3)

Evgesh-ka [11]

Answer:

plug in -3 where any x is in the equation. I reccomend doing it in parenthesis just so things work out nicely

Step-by-step explanation:

$x^2-x^3\\(-3)^2-(-3)^3\\(-3*-3)-(-3*-3*-3)\\(9)-(-27)\\9+27\\36$
