Answer 2

Given :

• Height of Cylinder (h) = 10cm
• Radius of Cylinder (r) = 5cm
• π = 3.14

To Find :

• Volume of Cylinder

Solution :

We know that,

⠀⠀⠀⠀★ Volume of Cylinder = πr²h

⟶⠀Volume = πr²h

⟶⠀Volume = 3.14 × (5)² × 10

⟶⠀Volume = 3.14 × 5 × 5 × 10

⟶⠀Volume = 3.14 × 25 × 10

⟶⠀Volume = 3.14 × 250

⟶⠀Volume = 314 × 250/100

⟶⠀Volume = 78,500/100

⟶⠀Volume = 785cm³

So Volume of the Cylinder is 785cm³
