Answer:

The factor is \frac{3}{2}.

Step-by-step 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}\times 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=\frac{3}{2}

Therefore, The factor is \frac{3}{2}.

Which of the following mixed numberd is represented by the letter A in number line shown?​
pentagon [3]

Answer:

A

Step-by-step explanation:

The line is divided into 9 parts between 1 and 2

A is situated 6 parts of the way between 1 and 2, that is

\frac{6}{9} = \frac{2}{3} ← cancelling by 3

Hence

A = 1 + \frac{2}{3} = 1 \frac{2}{3} → A
