These cylinders are similar. Find the volume of

Basile [38]

Answer:

$V_s=85\ cm^3$

Step-by-step explanation:

Let $V_s\ and\ V_b$ be the volumes of the smaller and bigger cylinder.

The formula for the volume of a cylinder is given by :

$V=\pi r^2 h$

As the two triangles are similar, the cube of their ratio would equal the ratio of their volume i.e.

$\dfrac{V_s}{V_b}=(\dfrac{h_s}{h_b})^3\\\\\dfrac{V_s}{V_b}=(\dfrac{3}{5})^3\\\\\dfrac{V_s}{V_b}=0.216\\\\V_s=393\times 0.216\\\\V_s=84.8\\\\or\\\\V=85\ cm^3$

So, the volume of the smaller cylinder is equal to $85\ cm^3$ .

Y=2x+5 and y=3x+2 using substitution strategy

WINSTONCH [101]

Answer:

Hi there the answer will be (3,11)

Since you are using the substitution way, you first plug in one of the y's into the other equation and you can see that they are set equal to each other.

2x+5=3x+2

Then you subtract 2x on both sides to get the x's on the same side

and you get 5=x+2

Then you subtract 2 on both sides, and you get x to equal to 3

then you plug x into any equation to get y to equal 11

y= 2(3)+5
