Two similar cylinders have volumes of 512π in.3

and 64π in.3
. By comparing volume, what is the scale factor of the small cylinder to the larger cylinder?(1 point)

5 answers

To find the scale factor of the smaller cylinder to the larger cylinder based on their volumes, you can use the formula for the ratio of the volumes of similar three-dimensional objects.

Given the volumes:

  • Volume of the larger cylinder \( V_1 = 512\pi \) in³
  • Volume of the smaller cylinder \( V_2 = 64\pi \) in³

To find the ratio of the volumes:

\[ \text{Volume Ratio} = \frac{V_2}{V_1} = \frac{64\pi}{512\pi} = \frac{64}{512} = \frac{1}{8} \]

Since the volumes of similar objects are related by the cube of the scale factor (if \( k \) is the scale factor):

\[ k^3 = \frac{V_2}{V_1} = \frac{1}{8} \]

To find the scale factor \( k \), take the cube root:

\[ k = \sqrt[3]{\frac{1}{8}} = \frac{1}{2} \]

Thus, the scale factor of the smaller cylinder to the larger cylinder is:

\[ \frac{1}{2} \]

this is wrong can you give me a difrent answer

Let's go through the problem again step by step to ensure we find the correct scale factor.

Given:

  • Volume of the larger cylinder, \( V_1 = 512\pi \) in³
  • Volume of the smaller cylinder, \( V_2 = 64\pi \) in³

First, we find the ratio of the volumes:

\[ \text{Volume Ratio} = \frac{V_2}{V_1} = \frac{64\pi}{512\pi} = \frac{64}{512} = \frac{1}{8} \]

When dealing with similar three-dimensional objects, the relationship between their volumes and the scale factor \( k \) is given by:

\[ \text{Volume Ratio} = k^3 \]

So we have:

\[ k^3 = \frac{1}{8} \]

To find \( k \), take the cube root of both sides:

\[ k = \sqrt[3]{\frac{1}{8}} = \frac{1}{2} \]

This indicates that the scale factor of the smaller cylinder to the larger cylinder is indeed \( \frac{1}{2} \).

If this interpretation is not what you were looking for, could you please clarify the criteria for the scale factor or any other detail you may be considering? Thank you!

im asking for the scale factor

I apologize for any confusion earlier. Let's clarify the proper scale factor based on the given volumes.

You provided:

  • Volume of the larger cylinder: \( V_1 = 512\pi \) in³
  • Volume of the smaller cylinder: \( V_2 = 64\pi \) in³

To find the scale factor of the smaller cylinder to the larger cylinder, we need to calculate the ratio of the volumes and then determine the cube root to get the linear scale factor.

  1. Calculate the volume ratio:

\[ \frac{V_2}{V_1} = \frac{64\pi}{512\pi} = \frac{64}{512} = \frac{1}{8} \]

  1. Relate the volume ratio to the scale factor:

Since the volumes are related by the cube of the scale factor \( k \):

\[ k^3 = \frac{1}{8} \]

  1. Find the scale factor \( k \):

Taking the cube root of both sides:

\[ k = \sqrt[3]{\frac{1}{8}} = \frac{1}{2} \]

Thus, the scale factor of the smaller cylinder to the larger cylinder is:

\[ \boxed{\frac{1}{2}} \]

If you are looking for the scale factor of the larger cylinder to the smaller cylinder, it would be \( 2 \), since the inverse of \( \frac{1}{2} \) is \( 2 \). Please clarify if this is what you want.
