2.2 cubic dm of brass is to be drawn into a cylindrical wire 0.25 cm in diameter. Find the length of the wire.

Text Solution

Verified by Experts

Diameter=`0.25cm`
Radius=`(0.25-:2cm)`=`(0.25-:20)dm`
Volume of brass=Volume of cylinder
`22`=`(22-:7)xx(0.25-:20xx0.25-:20)xxh`
`h`=`44800dm`
Hence, length of the wire is `44800 dm`.
