Answer:

The factor is
(3)/(2).

Explanation:

Given : Cylinders A and B are similar solids.

The base of cylinder A has a circumference of
4\pi units.

The base of cylinder B has an area of
9\pi units.

To find : The dimensions of cylinder A are multiplied by what factor to produce the corresponding dimensions of cylinder B?

Solution :

Let x be the factor.

So, according to question,


\text{Dimension of cylinder A}* x = \text{Dimension of cylinder B} ........[1]

The dimension refer here are radius of both cylinders.

In cylinder A,

Circumference of base is
4\pi units.

Circumference of base of cylinder is
C=2\pi r


4\pi=2\pi r


r=2

The dimension of cylinder A is r=2

In cylinder B,

Area of cylinder is
9\pi units.

Area of base of cylinder is
A=\pi r^2


9 \pi=\pi r^2


r^2=9


r=3

The dimension of cylinder B is r=3

Substitute in [1]


2x=3


x=(3)/(2)

Therefore, The factor is
(3)/(2).
