To determine the volume of a figure after it has been dilated using a scale factor, you follow these steps:
-
Find the original volume (V) of the figure. This step usually requires you to either know or calculate the volume based on the dimensions provided (length, width, height, radius, etc.).
-
Apply the scale factor to the original volume. When a three-dimensional figure is dilated by a scale factor \( k \), the new volume \( V' \) can be calculated using the formula: \[ V' = k^3 \times V \] where \( k \) is the scale factor.
In this case, the scale factor \( k \) is 2. Therefore, you will calculate: \[ V' = 2^3 \times V = 8 \times V \]
- Calculate the final volume. Multiply the original volume by 8 (or the value of \( V \) once calculated).
If you have a specific volume for the original figure, you can substitute that volume into the equation to find the new volume after dilation. If you provide me with the original volume, I can help you calculate the new volume after dilation.
