The diameter of a

Volume of the metallic sphere=volume of the wire(cylinder in shape)

Radius of sphere cm

=4.5 cm

Volume of sphere = ³

³

Radius of cylinder = 1mm =0.1cm

Volume of cylinder r²h

⇒ πr²h ³

⇒ r²h R³

⇒ 0.1 × 0.1 × h = × 4.5 × 4.5 × 4.5

⇒ 0.1 × 0.1 × h =4 × 1.5 × 4.5 × 4.5

⇒ h = 12150 cm
