Answer:

A

Step-by-step explanation:

In geometry (or math in general), when you do a reflection, rotation, or translation the size or length of the lines don't change. Think about it this way: if I have a log and I bring it into the bathroom with me (don't ask why idk) and hold it up in from of the mirror, what will happen? It will look the same length (and people will think I'm crazy for bringing a log into the restroom with me... but I digress).

Answer:

The answer is "A"

Step-by-step explanation:

A reflection across a line is a rigid transformation. Therefore the shape of the original object will not change. Because of this, you know that it would have the same length as the original line segment.

I hope this helps!!!!

A tube is being stretched while maintaining its cylindrical shape. The height is increasing at the rate of 2 millimeters per sec
hoa [83]

Answer:

V = πr²h

S=2πrh

h= 2/3 millimeters

new height= 8/3 millimeters

S= 8π  millimeters square

New surface area = 32π  millimeters square

Step-by-step explanation:

The volume of the cylinder is given by V = πr²h   where r is the radius and h is the height.

The surface area of the cylinder is given by  S= 2πrh + 2πr²

Where πr² gives the area of the base and 2πr² gives the area of the top and bottom surfaces. The surface area S of a cylinder, not including the top and bottom of the cylinder, is therefore S=2πrh.

V = πr²h

96π= π (6*6) (h+2)

96 = 36 (h+2)

96/36= h+2

h= 96/36-2

h= 96-72/36

h= 24/36

h= 4/6

h= 2/3 millimeters

New height

h + 2= 2/3 + 2

= 2+6/3= 8/3 millimeters

Now S =2πrh

S = 2π(6) (2/3)

S= 8π  millimeters square

New Surface area

S = 2π(6) (8/3)

S= 32π  millimeters square
