If r=8 and h=4, what is the volume of the cylinder shown above

Inessa05 [86]

Lets get started :)

The Volume formula of a Cylinder is
V = $\pi$ r²h
(r = radius, h = height)

The radius given is 8 and the height is 4, We can plug in the known values

V = $\pi$ (8)²(4)
= $\pi$ 256
= 256 $\pi$ units³ (You can leave the answer in this form)
≈ 804.2 units³ (approximately)

Units³ because it is a volume (3D shape)

Determinați domeniul de definiție al funcției f:D→R, f(x)=(√2-3x)+2

Rudik [331]

Answer:

The domain is all real numbers less than or equal to two-third

Step-by-step explanation:

<u><em>The question in English is</em></u>

Determine the domain of the function f :D→R, $f(x)=\sqrt{2-3x}+2$

we know that

The radicand of the function must be greater than or equal to zero

so

$2-3x \geq 0$

Solve the inequality for x

subtract 2 both sides

$-3x \geq -2$

Multiply by -1 both sides

$3x \leq 2$

Divide by 3 both sides

$x \leq \frac{2}{3}$

The solution is the interval ----> (-∞,2/3]

therefore

The domain is all real numbers less than or equal to two-third

All side lengths of ΔJKL equal 2 units. A transformation maps ΔJKL to ΔJ'K'L'. The length of side J'K' is 5 units. Is this a rig

S_A_V [24]

No because at least one segment length is not preserved.
rigid means everything stays the same, but orientation sometimes changes.
