Question

What is the volume of a cylindrical pipe of height 14 m and radius 3 m?
1. 296 m3
2. 478 m3
3. 396 m3
4. 378 m3

Answer 1

Correct Answer - Option 3 : 396 m3

Given:

The radius of cylindrical pipe = 3 m

Height of cylindrical pipe = 14 m

Formula Used:

Volume of cylinder = πr2h

Calculation:

The volume of cylindrical pipe = πr2h

⇒ (22/7) × (3)2 × 14 

⇒ 22 × 9 × 2 

⇒ 396 m3

∴ The volume of the cylindrical pipe is 396 m3.
