Roll a rectangular piece of paper 12.56 cm long and 9.42 cm wide into a cylinder. The volume of the cylinder is______ Cubic centimeter or______ Cubic centimeter

(1) 3.14 × 9.42, = 3.14 × 22 × 9.42, = 12.56 × 9.42, = 118.3152 (cubic centimeter); (2) 3.14 × 12.56, = 3.14 × 1.52 × 12.56, = 7.065 × 12.56, = 88.7364 (cubic centimeter); so the answer is: 118
