Remember that the volume of a cylinder is

\begin{gathered} V=\pi\cdot r^2\cdot h \\  \end{gathered}

so we have that

r=\sqrt[]{\frac{V}{\pi\cdot h}}=\sqrt[]{\frac{1909.92384}{3.14\cdot6.6}}=\sqrt[]{92.12}=9.6

so the radius is 9.6 milimeters

Plz help me with this i do not understand math stuff
Zarrin [17]

Answer: Pink choice: y= -6x -2

Step-by-step explanation:

In order to be parallel, the slope must be the same. You find the slope as the number or fraction connected to x. <em>("co-efficient" of x in math talk)</em>

In the given equation, that is -6.  (So that knocks out the first two choices)

The other thing to look at is the y-value of the given coordinate,(-1,4)

<em>(The y-value is the second number in the coordinate (x.y) is the pattern)</em>

and compare it to the the last number in the equations in the choices and     Here the Yellow choice has y= -6x + 4 so this line can't pass through the coordinate given, because  +4 in this equation is where the line crosses the y-axis. ("y-intercept"  in math talk)  So yellow choice is out!

The attachment shows what the graphs of the choices look like.

The black line is the correct answer. The given coordinate (-1,4) is the labeled red spot. The blue line is the given equation. (You can see where it "intercepts the y-axis on the +3)   And the green line also has the -6 slope, but misses the point and intercepts the y-axis at 4.)    

I hope the diagram and explanation helps you understand better. It can be confusing.

pentagon [3]

Answer:

Brian has $776 more account in his account than Chris.

Step-by-step explanation:

Compound interest Formula:

A=P(1+r)^t

I= A-P

A= Amount after t years

P= Initial amount

r= Rate of interest

t= Time in year

Given that,

Brian invests $10,000 in an account earning 4% interest, compounded annually for 10 years.

Here P = $10,000 , r= 4%=0.04, t=10 years

The amount in his account after 10 years is

A=10000(1+0.04)^{10}

   =$14802.44

  ≈$14802

Five years after Brian's investment,Chris invests $10,000 in an account earning 7% interest, compounded annually for 5 years.

Here P = $10,000 , r= 7%=0.07, t=5 years

The amount in his account after 5 years is

A=10000(1+0.07)^{5}

   =$14025.51

  ≈$14026

From the it is cleared that Brian has $(14802-14026)=$776 more account in his account than Chris.

What are congruent triangles. ​
pashok25 [27]

Answer:

Congruent triangles are triangles that have the same size and shape.

We say that the two triangles are congruent if their corresponding sides are equal in length, and their corresponding angles are equal in measure.

I am confused on how to do this
babymother [125]
So, u would start by expanding the bracket and ignoring the 2 at the moment.
(x+9)(x+9)= x^2-18x+81(using the foil method!

Then u would put 2 at the front to get:
2(x^2+18x+81)
= 2x^2+36x+162

Solve the triangle give the measure of y
pishuonlain [190]

Given:

In triangle BGU,BG=x,GU=7,BU=y,m\angle U=90^\circ,m\angle B=44^\circ.

To find:

The value of y.

Solution:

In a right angle triangle,

\tan \theta=\dfrac{Perpendicular}{Base}

In triangle BGU,

\tan B=\dfrac{GU}{BU}

\tan 44^\circ=\dfrac{7}{y}

0.966=\dfrac{7}{y}

Isolating y, we get

y=\dfrac{7}{0.966}

y=7.2463

y\approx 7.2

Therefore, the correct option is A.
