Answer:
Option (4).
Step-by-step explanation:
Outer diameter of the hollow metallic ball = 10 centimeters
Outer radius of this ball = = 5 cm
Volume of the outer ball =
=
Inner radius of the hollow metallic ball = (5 - 1) = 4 cm
Volume of the inner hollow ball =
Volume of the metal used in the metallic ball =
=
=
Therefore, expression given in option (4) will be used to measure the volume of the hollow metallic ball.
