ANSWER

Given a metal cuboid of dimension length 22 cm breadth 15 cm and height is 7.5 cm

Then volume of cuboid =22×15×7.5=2475cm3

If we melt this cuboid and cast in the cylinder of height 14cm

Then the volume of cuboid =volume of cylinder

Let r is a radius of a cylinder

Then volume of cylinder =πr2h=722×r2×14

∴722×r2×14=2475

⇒r2=22×142475×7=56.25

⇒r=7.5cm
