Three solid metallic balls of radii, 3 cm, 4cm and 5 cm are
melted and moulded into a single solid ball. The radius of the
new ball is
Read Solution (Total 1)
-
- 6 cm
Total volume of three metallic balls(spheres)= (4/3)*Pi*(3^3+4^3+5^3)
=(4/3)*Pi*216= Volume of new ball with radius 'r'
so (4/3)*Pi*r^3=(4/3)*Pi*216
r^3=216 , r=6 - 8 years agoHelpfull: Yes(0) No(0)
