​

Answer 1

FINAL ANSWER:-

length of iron rod ⇒ $700\:cm$

GIVEN:-

An right circular cylindrical iron rod is made after melting 550 cm³ iron

the diameter of the rod is 1 cm

TO FIND:-

length of iron rod

FORMULAS USED:-

$volume \:of \:cylinder= \pi r^{2} h$

SOLUTION:-

volume of cylinder =550

$550= \pi r^{2} h\\550=\frac{22}{7}* 0.5*0.5*h\\h=\frac{550*7}{22*0.5*0.5}\\h=100\:cm$
