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
