A right triangle with three sides of 3cm, 4cm and 5cm is rotated around the shortest right side to get a right triangle And its volume is ．

(1) Take the right angle side AB as the axis to rotate one circle, we can get a solid figure, which is a cone; (2) 13 × 3.14 × 42 × 3 = 13 × 3.14 × 16 × 3 = 50.24 (cubic centimeter); so the answer is: cone, 50.24 cubic centimeter
