The question is incomplete. The complete question is :
Cylinders A and B are similar. The length of the cylinder A is 4 mm and the length of cylinder B is 6 mm. The volume of cylinder A is 20mm3. Calculate the volume of cylinder B.
Answer:
67.5 
Step-by-step explanation:
Given that :
Cylinder A and cylinder B are similar.
Let volume of cylinder A = 20 
We know the volume of a cylinder is given by V = 
where, r is the radius of the cylinder
h is the height of the cylinder
We have to find the scale factor.
The length scale factor is = 

Area scale factor 

∴ Volume scale factor 

Therefore, the volume of cylinder B is 
= 67.5 
I'll treat these like they're two seperate problems because how you set it up they're not together. If it's one whole problem please tell me and I'll solve it that way. :-)
First one: 3x+9+8x + 12
Collect like terms and simplify
(3x+8x)+(9+12)
11x+21
Second one: 2x + 6+x² + 6x + 9
Collect like terms and simplify

8x+15+
Hope this helps you, have a BLESSED and wonderful day, as well as a safe one!

Step-by-step explanation:
a function that describes a set of points in Cartesian space by mapping each x-coordinate to a y-coordinate, then a circle cannot be described by a function because it fails what is known in High School as the vertical line test. A function, by definition, has a unique output for every input.
<span>-12 = pico(p)
So 10^-12 L = 1 pL
Use following to find the count of 10^-12 L are there in 2.3×10^-10 L
2.3×10^-10 / (10^-12) = 2.3×10^2 = 230 pL
-6 = micro (µ)
4.7×10^-6 g = 4.7 µg
1.85×10^-12 m = 1.85 pm
6 = Mega (M)
16.7×10^6 s = 16.7 Ms
So the answer is 16.7 Ms</span>
