A cone has a volume of 5 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?
DENIUS [597]
The answer is 15 in³.

The volume of the cone is:
V_1= \pi r_1 ^{2}  \frac{h_1}{3} = \frac{ \pi  r_1^{2} h_1}{3}
where:
V₁ - the volume of the cone
r₁ - the radius of the cone
h₁ - the height of the cone

The volume of the cylinder is:
V_2= \pi  r_2h_2^{2}
where:
V₂ - the volume of the cone
r₂ - the radius of the cone
h₂ - the height of the cone

Since <span>the cone fits exactly inside of the cylinder, they have the same radius and the height:
r</span>₁ = r₂
h₁ = h₂

Also:
V₁ = 5

Now, let's write two volume formulas together:
V_1= \frac{ \pi r^{2} h}{3}
<span>V_2= \pi rh^{2}</span>

We can include V₂ into V₁:
V_1= \frac{V_2}{3}

⇒ V_2=3*V_1
V_2=3*5 in^{3}
V_2=15 in^{3}

(-1,-2) and (3, -162) a. Is there a line th(at goes through these two points? How do you know? If there is one, what is the equa
lana [24]

Answer:

The equation of line for given points is y = - 40 x - 42  

Step-by-step explanation:

Given two points as :

( -1 , - 2 )  and ( 3 , - 162 )

Now, Equation of line in points form

y - y_1 = m × ( x -  x_1 )

Where m is the slope of line

And, m = \frac{y_2 - y_1}{x_2 - x_1}

or, m = \frac{ - 162 + 2}{ 3 + 1}

or, m =  \frac{ - 160}{ 4}

∴   m = - 40

So, Slope of line for given points is - 40

Now equation of line can be written as

y - ( - 2 ) = ( - 40 ) × ( x -  ( - 1 ) )

or, y + 2 =  ( - 40 ) × ( x + 1 )

or, y + 2 = - 40 x - 40

or, y = - 40 x - 40 - 2

∴  y = - 40 x - 42        

Hence the equation of line for given points is y = - 40 x - 42    Answer

Please help me ASAP easy problem giving brainlist!!
never [62]

Answer:

x ≥ 1

Step-by-step explanation:

Since it's a closed circle x could also be equal to 1. Also, since the arrow is pointing away from 1 the answer of x is greater than 1, therefore the answer is x ≥ 1.
