Question

a solid sphere of radius 1 CM is melted in stretched into a wire of length 100 CM. find the radius of wire.

Answer 1

Wire is cylindrical Volume of sphere = volume of cyclinder let r1 be sphere radius and r2 be radius of wire 4/3 pie r1 cube = pie r2 square h (pie pie cancelled) then 4/3 1 cube = r2 Square 100 (100 other side) the 4/300 = r2 square (square this side become root) 2/10 root 3

Answer 2

Hope it's correct
More accurate will be 1/5√3
