Answer:
64 m³
Step-by-step explanation:
For similar figures
linear ratio = a : b , then
area ratio = a² : b² and
volume ratio = a³ : b³
Given
area ratio = 64 : 144 , then
linear ratio =
:
= 8 : 12 = 2 : 3
Then
volume ratio = 2³ : 3³ = 8 : 27
let volume of smaller cylinder be x, then
=
( cross- multiply )
27x = 8 × 216 = 1728 ( divide both sides by 27 )
x = 64
Volume of the smaller cylinder = 64 m³

Sorry if it is wrong
Answer:
y=3x-2 (d)
Step-by-step explanation:
First, we need to look at the y-intercept, we can see that when x = 0, y= -2. So then our equation has to be y=mx+b, and b is -2. next we find our slope, we can see that we go up by 3, then over 1, so our slope is 3/1 or 3. so the final equation is y=3x-2.
Hope this helps!

Answer:
3. 2x+18=4x+26
Step-by-step explanation:
2(x+9)=4(x+7)+2
2x+18=4x+28+2
