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 : |
8 : 9 9 : 8 7 : 13 12 : 13 |
9 : 8 |
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 |
