Question Analysis
This question tests the understanding of the key properties of similar cylinders.
The main focus is differentiating correct and incorrect statements related to the characteristics of similar cylinders.

Key Concept Explanation
Similar cylinders maintain the same shape, meaning the ratio of their radii is equal to the ratio of their heights.
Volume, surface area, and height can vary among similar cylinders.

Step-by-Step Solution
Option A: Similar cylinders can have different volumes as they vary in size, so this is incorrect.
Option B: This is the correct property of similar cylinders, as the shape is maintained when the ratio of radii and heights is the same.
Option C: Similar cylinders don't need ...
