Expand the side of a cylinder to get a square. Given that the height of the cylinder is 12.56 decimeters, calculate the volume of the cylinder

Expand the side of a cylinder to get a square. Given that the height of the cylinder is 12.56 decimeters, calculate the volume of the cylinder

12.56÷3.14÷2=2﹙dm﹚
2²×3.14×12.56=157.7536﹙dm²﹚
