8. Congruent and Similar Solids
Sign In
Begin by finding the scale factor of the solids.
380.7 π cm^3
We have two similar cylinders whose heights are 23 cm and 8 in.
Now we can find the scale factor. The ratio of the height of the first cylinder to the height of the second cylinder will give us the scale factor. Scale Factor 23/20.32≈ 1.13 ⇔ 1.13 : 1 The scale factor is about 1.13:1. Next, we will recall Theorem 12.1 to relate the scale factor to the ratio of the volumes..
Theorem 12.1 |
If two similar solids have a scale factor of a:b, then the ratio of the surface areas is a^2:b^2, and the ratio of the volumes is a^3:b^3. |
