What’s the answer to this question? I’m confused as to how to do this.

Answer:

x = 20

Step-by-step explanation:

(3x + 50) = (6x - 10)

Subtract 6x on each side

3x + 50 - 6x = -10

Combine the x values together

-3x + 50 = -10

Subtract 50 on each side

-3x = -60

Divide each side by -3

x = 20

A cylinder has a radius of 10cm and a height of 9cm. A cone has a radius of 10cm and a height of 9 cm. Show that the volume of t

nlexa [21]

Answer:

The answer in the procedure

Step-by-step explanation:

step 1

Find the volume of the cylinder

The volume of the cylinder is equal to

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

we have

$r=10\ cm$

$h=9\ cm$

substitute

$V=\pi (10)^{2}(9)=900\pi\ cm^{2}$

step 2

Find the volume of the cone

The volume of the cone is equal to

$V=(1/3)\pi r^{2} h$

we have

$r=10\ cm$

$h=9\ cm$

substitute

$V=(1/3)\pi (10)^{2}(9)=300\pi\ cm^{2}$

therefore

we have

$Vcylinder=900\pi\ cm^{2}$

$Vcone=300\pi\ cm^{2}$

so

$Vcylinder=3Vcone$
