The ratio of the volume of pipe a to the volume of pipe b is 27:1 .
<h3>What is cylinder?</h3>
A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder.
Given that,
Radius of pipe a is 6 cm, and the radius of pipe b is 2 cm.
We know that the volume of cylinder is :- 
where r is radius and h is height of the cylinder.
If two figures are similar then ratio of volume is equal to the cube of any dimension.
The ratio of the volume of Pipe a to the volume of Pipe b :-

= 
Hence, The ratio of the volume of pipe a to the volume of pipe b is 27:1 .

Well what +8 will be -11.
Let’s take this as positives.
8+11=19
Sooo
-19+8=-11
C=-19
The value of 3 would be 3,000.
Why thousands? Well because u have to count from the right, then back, so ones, tens, hundreds, then thousands lands on 3 so hope this helps.
Answer:
33
Step-by-step explanation:
49-15=34
34/17=2
For this sequence, you can write this function:
f(x)=15+2(x-1)
Check:
f(18)=15+2(18-1)
f(18)=15+2(17)
f(18)=15+34
f(18)=49
So:
f(10)=15+2(10-1)
f(10)=15+2(9)
f(10)=15+18
f(10)=33
Answer:
1/9 is probably most likely the correct answer
