Question

a solid sphere of radius 3cm is melted and reformed by streching it into a cylindrical shaped wire of length 9m. find the radius of the wire ​

Answer 1

Answer:

radius of bigger sphere(R) = 3 cm

radius of smaller balls(r) = 0.6/2 = 0.3 cm

let the number of small balls = n

n×volume of a small balls = volume of bigger sphere

n*4/3πr³ = 4/3πr³

n = R³/r³

n = (R³/r³)

n = (3/.03)³ = (10)³

n = 1000

Number of small balls is 1000.
