volume of 1st cylinder=πr²h
                                   =22/7*2.5*2.5*4
                                  =78.57
 volume o 2nd cylinder=πr²h
                                    =22/7*2.5*2.5*6
                                    =117.85

volume of sphere=78.57+117.85
                           =196.42

volume of sphere=1/3πr³
                     196.42 =1/3*22/7 *r³
               196.42*3*7/22*1=r³
                         187.49=r³
                            r=∛187.42
                            r=5.72
