A cylinder and a cone have the same circumference and height at the bottom. The volume of the cone is 3.6 cubic decimeters, and the volume of the cylinder is 3.5 cubic meters

A cylinder and a cone have the same circumference and height at the bottom. The volume of the cone is 3.6 cubic decimeters, and the volume of the cylinder is 3.5 cubic meters

For a cylinder and a cone, the perimeter and height of their bottom surface are equal, which means that their bottom area and height are equal
The volume of cylinder is 3.6 × 3 = 10.8 cubic decimeter
