AS we know that:

$V=SA*h$

And we have the volume and we can calculate the SA,,,

So that, we can conclude:
$h= \frac{V}{SA} = \frac{323.5}{\pi (7)^2} =2.1015~~in$

Are you satisfied?

Answer:

$\huge\boxed{7\ \text{inches}}$

Step-by-step explanation:

As I mentioned earlier with a single side (line), rotations do not change the size of something. Only dilations do that. This goes for both lines AND shapes.

However, if the question said she dilated the piece, then yes, the length in inches would be different. However, rotation just changes the position and nothing happens to the length.

Hope this helped!
