Question

find the volume of cylinder if radius 21 cm and height 7 cm​

Answer 1

Step-by-step explanation:

The volume of cyclinder = ♫ r^2 h

so 3.14* 21*21*7 = 9698.1 cm^2

Hope you understand

Answer 2

Given :

• Radius of Cylinder = 21cm
• Height of Cylinder = 7cm

To Find :

• Volume of Cylinder

Solution :

⠀⠀⠀⠀⠀★ Volume of Cylinder = πr²h

⠀⟶⠀Volume = πr²h

⠀⟶⠀Volume = 22/7 × (21)² × 7

⠀⟶⠀Volume = 22/7 × 21 × 21 × 7

⠀⟶⠀Volume = 22 × 21 × 21

⠀⟶⠀Volume = 22 × 441

⠀⟶⠀Volume = 9702cm³

So, Volume of Cylinder is 9702cm³

More Formulas (Cylinder) :

• Volume = πr²h
• Curved Surface Area = 2πrh
• Total Surface Area = 2πr(h + r)
• Area of Base/Top = πr²h
