A right circular cone is cut parallel to base in 3 parts each having a
Right Answer is: C
We have cut the cone in three parts parallel to the base: upper part having volume , middle part having volume and lower part having volume V3
We know that, if two cones are similar then the ratio of their volumes will be equal to the cube of the ratio of their corresponding heights.
⇒ V3 = 19k
So: V1 : V2 : V3= k:7k:19k =1:7:19
