NO LINKS!!! QRSTU ~ FGCDE. Find FG, CD, and EF.

arsen [322]

Answer:

See below ~

Step-by-step explanation:

Given :

QRSTU ~ FGCDE

Finding the scale factor :

Take two corresponding sides in proportion
RS : GC
40 : 12
10 : 3

Applying the scale factor to find the missing sides :

- FG :

QR : FG = 10 : 3
30/FG = 10/3
FG = 30/10 x 3
FG = 3 x 3
FG = 9

- CD :

ST : CD = 10 : 3
40/CD = 10/3
CD = 40/10 x 3
CD = 4 x 3
CD = 12

- EF :

UQ : EF = 10 : 3
30/EF = 10/3
EF = 30/10 x 3
EF = 3 x 3
EF = 9

The volume of a cylinder is 4 pi x3 cubic units and its height is x units.

Rzqust [24]

Answer:

$2x$

Step-by-step explanation:

The volume of a cylinder, $V$ is given by the formula,

$V=\pi r^{2}h$

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

Here, $V=4\pi x^{3}$ , $h=x$ . Plug in these values and solve for radius, $r$ .

This gives,

$V=\pi r^{2}h\\4\pi x^{3}=\pi r^{2}x\\r^{2}=\frac{4\pi x^{3}}{\pi x}\\r^{2}=4x^{2}\\$

Taking square root both sides, we get

$\sqrt{r^{2}}=\sqrt{4x^{2}}\\r=2x$

Therefore, the radius of the cylinder can be expressed as $2x$ .
