Answer:

452.16 cubic units

Step-by-step explanation:

Volume of cylinder

$= \pi {r}^{2} h \\ \\ = 3.14 \times {6}^{2} \times 4 \\ \\ = 3.14 \times 36 \times 4 \\ \\ = 452.16 \: {units}^{3}$

The real numbers $x$ and $y$ are such that \begin{align*} x + y &= 4, \\ x^2 + y^2 &= 22, \\ x^4 &= y^4 - 176 \sqrt{

tamaranim1 [39]

You get everything you need from factoring the last expression:

$x^4-y^4=-176\sqrt7$

The left side is a difference of squares, and we get another difference of squares upon factoring. We end up with

$x^4-y^4=(x^2-y^2)(x^2+y^2)=(x-y)(x+y)(x^2+y^2)$

Plug in everything you know and solve for $x-y$ :

$-176\sqrt7=(x-y)\cdot4\cdot22\implies x-y=\boxed{-2\sqrt7}$

If you borrow $675 for six years at a interest rate of 10% how much interest will you pay

murzikaleks [220]

Answer:

the answer is $40.5

Step-by-step explanation:

the basic formula of finding our interest is I = PxRxT

P (principal) = 675

R (rate) = 10% (we have to turn it into a decimal which is 0.010)

T (time) = 6 years

so :

I = 675 x 0.010 x 6

I = 40.5

What does the ratio of the circumference to the diameter represent? Explain

snow_tiger [21]

That is the exact representation of the constant π. By definition:

π=C/d, where C is the circumference of a circle and d is the diameter.
