Question

The diameter of a sphere is 24cm it is melted and drawn into a cylinder. wire of diameter 2•8cm find the length of wire​

Answer 1

Answer:

l = 1175.51 cm

Step-by-step explanation:

diameter of sphere = 24 cm

radius of the sphere ,R = 12 cm

diameter of wire = 2.8 cm

radius of wire , r= 1.4 cm

let l be the length of the wire

when it is melted and drawn to a wire,

volume of sphere = (4/3) x π x R^3

volume of cylinder = π x r^2 x l

volume of sphere = volume of cylindrical wire

(4/3) x π x R^3 = π x r^2 x l

(4/3) x 12^3 = 1.4^2 x l

l = 1175.51 cm
