If the radii of two cylinders are in the ratio of 2 : 3 and their heights are in the ratio of 5 : 3, then the ratio of their volumes is:
Answer & explanation
Correct answer: option 2
We know that,
Volume of a cylinder = πr2h
We have,
Ratio of radii = 2 : 3
Ratio of height = 5 : 3
Ratio volume of two cylinder = 22 × 5 : 32 × 3 = 20 : 27
