<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 .

Step-by-step explanation:
<em><u>well, this is easy</u></em>
<em><u>30% equals to 0.30 right.</u></em>
<em><u>we can't divide because if we do then the answer would be 50$ and that's way more money than Jill has.</u></em>
<em><u>so your wondering. What do we do?</u></em>
<em><u>Well, what's 30% of 15?</u></em>
<em><u>It's 4.5</u></em>
<em><u>4 dollars and 5 cents that U will have with Jill.</u></em>
