If a right circular cone is separated into solids of volumes V1, V2, V3 by two planes parallel to the base which also trisect the altitude, then V1 : V2 : V3 is
Answer & Solution
Correct Answer:
Option
D
Ratio of volume of bigger cone and smaller cone
= (Ratio of altitude)2
= (1 : 2 : 3)3
= (1 : 8 : 27)
∴ Ratio of parts
= 1 : 8 - 1 : 27 - 8
= 1 : 7 : 19
= (Ratio of altitude)2
= (1 : 2 : 3)3
= (1 : 8 : 27)
∴ Ratio of parts
= 1 : 8 - 1 : 27 - 8
= 1 : 7 : 19
