Question

Theradius of sphere is 9 cm . It is melted and drawn into a wire of diameter 2mm.Find length of wire

Answer 1

Answer:

Step-by-step explanation:

volume of sphere = 4/3*22/7*r*r*r

                                =4/3*22/7*9*9*9

volume of cylinder = 22/7*r*r*h

                                 =22/7*1/10*1/10*h

volume of sphere = volume of cylinder

4/3*22/7*9*9*9     =22/7*1/10*1/10*h

4*3*9*9                  =1/100*h

12*9*9                    =1/100*h

97200cm              = h

THUS , LENGTH IS 97200CM
