Correct Answer - Option 3 : 396 m

3
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.
