A) 6 cm
B) 9 cm
C) 18 cm
D) 36 cm
Correct Answer: A
Solution :
Volume of sphere = Volume of wire \[\frac{4}{3}\pi \times {{27}^{3}}=\pi \times {{r}^{2}}\times 729\] \[r=\sqrt{\frac{4\times 27\times 27\times 27}{3\times 729}}=\sqrt{36}=\] \[\therefore \] Radius of the wire = 6 cmYou need to login to perform this action.
