Use a piece of square paper with a side length of 2 decimeters to form an empty cylinder. The circumference of the bottom surface of the cylinder is Decimeter, height is Decimeter, side area is__ Square decimeter

The circumference of the bottom surface of the cylinder is: 2 decimeters; the height is: 2 decimeters; the side area of the cylinder is: 2 × 2 = 4 (square decimeters). Answer: the circumference of the bottom surface of the cylinder is 2 decimeters, the height is 2 decimeters, and the side area is 4 square decimeters
