If a cylinder and a cone are of equal height and equal bottom, the difference between their volumes is 18 cubic decimeters, then the volume of the cone is () cubic decimeters, and the volume of the cylinder is () cubic decimeters（
18 △ 3-1 = 9 cubic decimeter Volume of cone
9 × 3 = 27 cubic decimeter Volume of cylinder
Mathematical problems: 1: a cylinder and a cone have the same base and height, and the volume of the cone is 0.8 cubic decimeter less than the volume of the cylinder, so what is the volume of the cylinder and the cone?
There is a formula: the volume of a cone is one third of the volume of a cylinder with the same height and the same bottom
Let the volume of cone be x, then the volume of cylinder be 3x,
3x-x=0.8,
x=0.4,
3x=1.2.
If the volume difference between a cylinder and a cone is 18 cubic decimeters, what is the volume of the cone? What is the volume of the cylinder?
V-pillar = 3V cone 18 / 2 = 9 9 * 3 = 27 cylinder 27 cubic decimeter cone 9 cubic decimeter
