The ratio of the base cylinder and a cone is 3 : 4 and their heights are in the ratio 2 : 3. Then the ratio of their volume :
Answer & explanation
Correct answer: option 2
Ratio of the base radius of cylinder and a cone is B1:B2 = 3:4
heights are in the ratio h1:h2 = 2:3
Volume ratio= Πr12*h1 : Πr22*h2/3 = 32*2 : 42*3/3 = 18:16 = 9:8
The correct answer is option (2): 9 : 8
