Q. The ratio of the volumes of two cylinders is 8 : 27 and their heights are equal. The ratio of their radii is:
✅ Correct Answer: (D)
None of these
Explanation: Volume ∝ r². Radius ratio = √(8:27) is not 2:3, so this is only valid if volume ratio were 4:9. (This type is commonly asked; correct concept: radius ratio = √volume ratio.)

Volume ∝ r². Radius ratio = √(8:27) is not 2:3, so this is only valid if volume ratio were 4:9. (This type is commonly asked; correct concept: radius ratio = √volume ratio.)
