A sphere of diameter 3.0 cm is mounted into a thin uniform wire of diameter 0.2mm calculate the length of the wire in meters

3600 cm or 36 cm

Explanation:

for sphere,d=6,r=6/2=3cm

for cylindrical wire, d=0.2,r=0.2/2=0.1cm

let the length of wire be x cm

so, according to the question

volume of cylindrical wire = volume of sphere

πr2h =4/3πr3

0.1×0.1×x=4/3×3×3

x=4×3×3×3/0.1×0.1×0.1

x=3600 cm or 36 cm

Hope it's helps
