Question

A cubic meter of brass is drawn into a wire of diameter 2 cm. find the length of the wire ​

Answer 1

Answer:

given, diameter=2 so radius is 1cm

volume of brass = 1 m^3

volume of cube = volume of cylinder(wire)

1 = π×1×h (1m^3=1000000 cm^3)

1000000=22/7×h

1000000×7/22= h

7000000/22=h

318181.818181...=h ans...

Answer 2

The length of the wire is 318181.81 cm.

Step-by-step explanation:

Given : A cubic meter of brass is drawn into a wire of diameter 2 cm.

To find : The length of the wire ​?

Solution :

Let the length of the wire be 'x' cm.

Diameter of wire = 2 cm

Radius of wire = 1 cm

Volume of brass = 1 m³= 1000000 cm³

We know that,

Volume of cube = volume of cylinder (wire)

i.e. $a^3=\pi r^2 h$

$1000000=\frac{22}{7}\times 1^2\times h$

$h=\frac{1000000\times 7}{22}$

$h=318181.81$

Therefore, the length of the wire is 318181.81 cm.
