A copper wire, 3 mm in diameter, is wound about a cylinder whose length is 12 cm, and diameter 10 cm, so as to cover the curved surface of the cylinder. Find the length and mass of the wire, assuming the density of copper to be `8. 88g p e r\ cm^3`

Text Solution

Verified by Experts

Solution:
As we know,
Volume of the cylinder = `πr₁2h₁`, where` r₁` and h₁ are the radius and the length of the cylindrical wire
Height of cylinder,` h = 12 `cm
Diameter of cylinder, `d = 10 `cm
