Hey friend, Here is your answer-
diameter of sphere = 6cm
radius of sphere ,
r = 3 cm
Diameter of wire = 0.2 cm
it's radius = 0.1 cm
Let the length be h.
Volume of wire = Volume of sphere..... (given)
pie × r^2 × h = 4/3 pie × r^3
0.1 × 0.1 × h = 4/3 × 3 × 3 × 3
h = 4×3×3 / 0.1 × 0.1
h = 36 / 0.01
h= 3600 cm
h = 36 m
Therefore the length of wire is 36 m.
Hope it will help you
