Find volume of cylinder. circumference is 9 and height is 15
MAXImum [283]

Answer:

The volume is 945.26

Step-by-step explanation:

The volume is 945.26 (this is only if this is a right cylinder)

volume of right cylinder formula = πr^2h

r = 4.5

We know that the circumference is 9.

circumference = 2πr

so, you would have to divide 9 by 2 to get the radius which is 4.5

h= 15 (already given)

then just plug it in!

π4.5^2(15)

π4.5^2 = 20.25π

20.25 x π = 63.6172512352

63.6172512352 x 15 ≈ 945.26

The midpoint QR is M (-1,2). One endpoint is R (3,4). Find the coordinates of the other endpoint.
butalik [34]

M = (x₁ + x₂)/2  , (y₁ + y₂)/2

(-1, 2) = \frac{3 + x}{2} , \frac{4 + x}{2}

At this point, it is easier to separate the x's and y's into two different equations:

x's: -1 = \frac{3 + x}{2}

     -2 = 3 + x

     -5 = x

y's: 2 = \frac{4 + x}{2}

     4 = 4 + x

     0 = x

Answer: (-5, 0)

PLEASE HELP ME NOW!!
puteri [66]

Answer:

x=4+-2\sqrt{7}

Step-by-step explanation:

To solve, we need to take square root of both sides first:

(x-4)^2=28\\\sqrt{(x-4)^2} =+-\sqrt{28} \\x-4=+-\sqrt{28}

Now we use the property of radical shown below to simplify square root of 28:

Property:  \sqrt{x*y}=\sqrt{x} \sqrt{y}

Now, we have:

x-4=+-\sqrt{28}\\x-4=+-\sqrt{4*7}\\x-4=+-\sqrt{4}\sqrt{7}\\x-4=+-2\sqrt{7}

Now we take 4 to the other side and isolate x:

x-4=+-2\sqrt{7} \\x=4+-2\sqrt{7}

first answer choice is right.

The triangles are similar. If QR = 9, QP = 6, and TU = 19, find TS. Round to the nearest tenth.
Feliz [49]
QR=9
QP=6
TU=19
TS=?
Okay so the triangles are kindred, now the equation can be made
9/16=6/x
So now we are going to cross multiply
9x=114
Now divide both sides by
912 2/3
Your answer is:
TS=12.6
