Question 1141975: the volume of a right circular cone is 5 litres. calculate the volume of the two parts into which the cone is divided by a plane parallel to the base. one third of the way down from the vertex to the base. give your answer to the nearest ml

The volume of the original cone is 5 liters, or 5000 ml.
When the cone is cut by a plane parallel to the base, 1/3 of the way down from the vertex, the small cone produced is similar to the original cone, with a height 1/3 the height of the original cone.
Then, since the two cones are similar, the volume of the small cone is (1/3)^3 = 1/27 the volume of the original cone.
So the volumes of the two pieces are 1/27 of 5000 ml and 26/27 of 5000 ml.
You can do the calculations and rounding necessary to answer the question.
