An oblique cylinder has a radius of 10 units and slant

snow_tiger [21]

Answer:

$2,400\pi$ cubic units

Step-by-step explanation:

Given the cylinder has a base radius of 10 units.

And slant length of 26 units.

The formula for volume of an oblique cylinder is $\pi r^2h$

Where $r$ is the radius and $h$ is the height of cylinder.

We will now find height of cylinder using following equation.

$(slant\ length)^2=(radius)^2+(height)^2$

$26^2=10^2+(height)^2\\\\676=100+(height)^2\\\\676-100=(height)^2\\\\576=(height)^2\\\\\sqrt{576}=\sqrt{(height)^2}\\ \\24=height$

Now, the volume of cylinder would be

$=\pi r^2h\\=\pi(10)^2\times24\\=\pi 100\times24\\=2400\pi$ cubic units

Can someone please help me with this question?

zysi [14]

Answer:

AE = 9 units

Step-by-step explanation:

Based on the centroid theorem:

AX = ⅔ of AE

Given that AX = 6 units, where X is the centroid of ∆ABC, therefore:

6 = ⅔ of AE

6 = ⅔(AE)

Multiply both sides by 3

6*3 = ⅔(AE)*3

18 = 2(AE)

Divide both sides by 2

18/2 = AE

9 = AE

AE = 9 units

Given A(-2,8) and B(4,14), what is the y-intercept of the line AB?

Darina [25.2K]

Answer: C:10

Step-by-step explanation:

Equation of a line passes through (a,b) and (c,d) :

$(y-b)=\dfrac{d-b}{c-a}(x-a)$

Equation of line passes through A(-2,8) and B(4,14) will be :

$y-8=\dfrac{14-8}{4-(-2)}(x-(-2))\\\\\Rightarrow\ y-8= \dfrac{6}{6}(x+2)$

$\Rightarrow\ y-8=x+2\\\\\Rightarrow\ y= x+2+8\\\\\Rightarrow\ y=x+10$

For y-intercept , put x= 0 , we get y= 10

So, the y-intercept = 10

Thus , correct option = C:10
