Question

The diameter of a sphere is 6cm . It is melted and drawn into a wire of diameter 2mm. find the length of the wire?​

Answer 1

Answer:

For cylindrical wire,

d=0.2cm,r

2

0.2

=0.1cm

Let the length of wire be xcm

So, according to problem Volume of cylindrical wire Volume of sphere

=πr

x=

0.1×0.1×0.1

4×3×3×3

x=3600cm or 36cm

Answer 2

Step-by-step explanation:

Volume of sphere = volume of wire

4/3×π×3³ = π×(0.1)²×h

3600cm
