A) 36 cm
B) 360 cm
C) 3600 cm
D) 306 cm
Correct Answer: C
Solution :
Diameter of sphere = 6 cm Diameter of wire =0.2 cm Volume of cylindrical wire = Volume of sphere \[\Rightarrow \]\[\pi {{r}^{2}}h=\frac{4}{3}\pi {{R}^{3}}\] \[\Rightarrow \]\[h=\frac{4}{3}\times \frac{22}{7}\times {{3}^{3}}\times \frac{7}{22}\times \frac{1}{0.01}\] \[=\text{36}00\text{ cm}\] \[\therefore \] Length of wire is 3600 cm.
