Question

A spherical metal ball of diameter 3 cm is drawn into a wire and diameter 3 may find the length of wire

Answer 1

Answer:

Step-by-step explanation:

Sphere:d=3cm =>r=3/2cm

Wire:r'=3/2cm

Volume of sphere= volume of cylinder

4/3πr^3= πr'^2h

4/3 r^3= r'^2h

4/3 x 3/2 x 3/2 x 3/2= 3/2 x 3/2 xh

4/3 x 3/2 =h

h=2cm

Therefore the length of wire =2cm
