Scale factor = 1/2, New screen 46 in by 38 in.

Step-by-step explanation:

The dimensions of screen is 92 in. by 76 in.

It has a feature that splits the screen to allow you to watch 4 channels at once as shown in the below figure.

All four parts are equal.

Let the dimensions of new screen be x in. by y in.

2x=92 and 2y=76

Divide both sides by 2.

x=46 and y=38

Scale factor is

$\text{Scale factor}=\frac{\text{New dimension}}{\text{Corresponding original dimension}}$

$\text{Scale factor}=\frac{46}{92}$

$\text{Scale factor}=\frac{1}{2}$

Therefore, the scale factor is 1/2.

Step-by-step explanation:

$V=h\pi r^2\\ \\ h=\frac{V}{\pi r^2}\ V=144\pi \ r=2in\\ \\ h=\frac{144\pi }{\pi 2^2}\\ \\ h=\frac{144}{4}\\ \\ h=36in$
