Question

A cubic of metal each of whose sides masures 2.2cm is melted to form a cylidrical wire of radius 1mm

Answer 1

I think you need the length of the wire... even though you haven't specifically mentioned it in your query. Kindly write the whole questions from next time...it won't cause any difficulty to other people to provide you with an answer.

Answer 2

Answer:

First we have to find the volume of cube

Volume of Cube = l^3(length cube) = l*l*l

                           = 2.2^3 = 2.2*2.2*2.2 = 10.648

                           = 10.648 cubic cm

Then we have to calculate according to the volume of given cube

Volume of Cylinder = πr^{2}h

    10.648 cubic cm = 22/7×2.2^{2}×h

                    10.648 = 22/7×4.84×h

           10.648÷4.84 = 22/7÷4.84×4.84÷4.84×h

                          2.2 = 3.08×1×h

                3.08÷2.2 = h

                             h = 1.4 cm

I hope it is correct please mark me as brainliest .

Thank You
