If the heights of two cylinders are in the ratio 2 : 3 and their- radius are in the ratio of 6 : 5, then what is the ratio of the volume of the cylinders ?
Answer & explanation
Correct answer: option 3
The ratio of the height = 2 : 3
The ratio of the radius = 6 : 5
Now the ratio of their volume = \(\frac{R^2 × H}{r^2 × h}\)
= \(\frac{6^2 × 2}{5^2 × 3}\)
= \(\frac{72}{75}\) = 24 : 25
