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.
