Question
If the Diameter of the metallic sphere is 6 cm , it melted and a wire of diameter 0.2 cm is drawn. Then , what would be the length of the wire ?
Hint:
The volume of sphere = 
The volume of cylinder = 
The correct answer is: 3600mm.
Explanation:
- We have given diameter of the metallic sphere is 6 cm , it melted and a wire of diameter 0.2 cm is drawn.
- We have to find the length of the wire.
Step 1 of 1:
We have diameter of metallic sphere 6cm
Radius of metallic sphere 3cm
Also we have diameter of cross-section of cylinder wire 0.2cm
So, Radius of cross-section of cylinder wire 0.1cm
Let the length of the wire be hcm
Since the metallic sphere is converted into cylindrical shaped wire of length hcm
Volume of metal used in wire is equal to volume of sphere
So,
0.01h = 36
h = 3600 cm
Therefore, The length of the wire is 3600cm.
