Expand the side of a cylinder to get a square with side length of 6.28 decimeters. The volume of the cylinder is () cubic decimeters A. 2B. 2πC. 19.7192

Expand the side of a cylinder to get a square with side length of 6.28 decimeters. The volume of the cylinder is () cubic decimeters A. 2B. 2πC. 19.7192

2 × 6.28, = 3.14 × 1 × 6.28, = 19.7192 (cubic decimeter), answer: the volume of the cylinder is 19.7192 cubic decimeter; so choose: C
