2 answers:

8 0

Volume is = to, pi x radius^2 x height. Length or diameter is the radius times 2. The radius would therefore be 6. So it comes down to
Pi x 6^2 x 5
Pi x 36 x 5
This can be easily solved in calculator

Answer:

okay let's start

Step-by-step explanation:

$v = \pi \: r\: ^{2} h \\ h = 5 \: r = (12) \div 2 = 6 \\ v = \pi \times 6 ^{2} \times 5 \\ = 565.4866776$

sergejj [24]

Answer:

x=8

Step-by-step explanation:

set up a proportion:

$\frac{20}{4}=\frac{4x-7}{5}$

simplify:

$5 =\frac{4x-7}{5}$

now solve this equation for x:

$5 = \frac{4x-7}{5} \\25 = 4x - 7\\32 = 4x\\x = 8$

Super confused definitely need help on this

Marat540 [252]

Answer:

$(x-5)(x+8)=x^2+3x-40$

Step-by-step explanation:

So we have the expression:

$(x-5)(x+8)$

To multiply, distribute the left to the terms on the right:

$=(x-5)(x)+(x-5)(8)$

Distribute:

$=(x^2-5x)+(8x-40)$

Combine like terms:

$=(x^2)+(-5x+8x)+(-40)$

Simplify:

$=x^2+3x-40$

Therefore:

$(x-5)(x+8)=x^2+3x-40$

What is the distance between the point (−10, −2)(−10, −2) and the point (−4, −2)(−4, −2) ?

Gnoma [55]

In this case: x 1 = - 10, y 1 = - 2;
x 2 = - 4 , y 2 = - 2
The distance between the points :
$d = \sqrt{(x 2 - x 1 ) ^{2} + ( y 2 - y 1 ) ^{2} } = \\ =\sqrt{(-4+10) ^{2} +(-2+2) ^{2} } = \\ = \sqrt{6 ^{2}+0 ^{2} } = \sqrt{36}= 6$
Answer: d = 6
