Answer 2

Given :

It is given that the radius of cylinder is 2r cm and Height is 3h cm

To find :

Volume of cylinder.

Solution :

We know that,

Volume of cylinder = πr²h

= 22/7 × (2)² × 3

= 22/7 × 4 × 3

= 37. 7 cm²

Therefore,

The Correct Answer is 37. 7 cm²

More to know :

• Volume of Cuboid = L × B × H
• Volume of Cube = (Edge)³
• Volume of cylinder = πr²h
• Volume of Hemisphere = 2/3πr³
• Volume of Sphere = 4/3πr³
