Step 1:  Note down the given information

                 cylindrical  shape height h = 11 cm

                                   Base diameter = 7 cm

                                              Radius  = \frac{7}{2} = 3.5 cm


Step 2: Find the volume of the cylindrical shape iron rod

                      Volume of the cylinder = \pi r^2 h

                                                          = \frac{22}{7} * (3.5)^2 * 11

                                                          = 423.5 cm^3    


Step 3: Calculating the total volume of 50 rods

                Volume of the one rod(cylinder) =   423.5 cm^3

                Total volume of the  50 rods = 50 * 423.5 cm^3

                                                             = 21175 cm^3
