into a cylindrical wire of diameter of cross section 0.2 cm. Determine
the length of this wire.
please answer me fast ..​

Answer 1

Answer:

According to given question,

According to given question,Let length of wire be l,

According to given question,Let length of wire be l,Diametre of wire is  4mm,

According to given question,Let length of wire be l,Diametre of wire is  4mm,so, radius will be  2mm

According to given question,Let length of wire be l,Diametre of wire is  4mm,so, radius will be  2mmVolume of metallic sphere = volume of cylindrical wire

According to given question,Let length of wire be l,Diametre of wire is  4mm,so, radius will be  2mmVolume of metallic sphere = volume of cylindrical wire⟹34π(9cm)3=π(2×10−1cm)2l

According to given question,Let length of wire be l,Diametre of wire is  4mm,so, radius will be  2mmVolume of metallic sphere = volume of cylindrical wire⟹34π(9cm)3=π(2×10−1cm)2l⟹l=24300cm=243m
