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 .

Answer:
It would be 36
Explanation:
<em>First:</em>
<em>Convert any mixed numbers to fractions.</em>
<em>Then your initial equation becomes:</em>
<em>108/1 ×1/3</em>
<em> </em>
<em>Applying the fractions formula for multiplication,</em>
<em>=108×1/1×3 = 108/3</em>
<em> </em>
<em>Simplifying 108/3, the answer is</em>
<em>=36</em>

Answer:
4a. 13
4b. -4
Step-by-step explanation:
2x-6/5 = 4 (Muti each side by 5)
2x-6 = 20
2x = 26 (Divide each side by 2)
x = 13
7- 2x/4 = 9
-2x/4 = 2 (Muti each side by 4)
-2x = 8 (Divide each side by -2)
x = -4
