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=2475cm
3
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 =πr
2
h=
7
22
×r
×14
∴
×14=2475
⇒r
=
22×14
2475×7
=56.25
⇒r=7.5cm
