Question

The diameter of a sphere is 42 om. It is meted and drawn into a cylindrical wire by 28
cm diameter. Find the length of the cylinder

Answer 1

Answer:

Step-by-step explanation:

Answer:

63 cm

Step-by-step explanation:

Diameter of sphere = 42 cm

Radius of sphere = 42/2 = 21 cm

Volume of Sphere =  

                             =  

Diameter of cylinder = 28 cm

Radius of cylinder = 28/2=14

Since we are given that sphere is melted and drawn in to a cylindrical wire .

So, Volume will remain same .

Thus the length of wire is 63 cm.
