Question

Geometry question, please help me

Answer 1

Hi there!

First, let's find the proportion of the radius' and set it equal to the proportion of the heights:
12/10 = 30/25

Next, we'll cross multiply. If the numbers are the same, then the solids are similar.
300 = 300

The solids are similar! The scale factor from the larger solid to the smaller solid is 6/5 or 1.2. The scale factor from the smaller solid to the larger solid is 5/6.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
