Question

if the radius of the base of the cylinder is 7cm and its height is 15cm then find its volume.
solve step by step​

Answer 1

Given :

✰ Radius of cylinder = 7cm

✰ Height of cylinder = 15cm

To Find :

✰ Volume of cylinder

Solution :

✰ As in the question Radius and height of the cylinder Is given. And we have to find the volume of cylinder. We can find volume of cylinder by Using formula πr²h Where π is 22/7 and r is radius and h is Height of the cylinder.

Volume of cylinder = πr²h

Where,

• Radius (r) = 7cm

• Height (h) = 15cm

→ 22/7 × (7)² × 15

→ 22/7 × 7 × 7 × 15

→ 22/7 × 49 × 15

→ 22 × 7 × 15

→ 2310cm³

∴ Volume of cylinder is 2310cm³

Answer 2

Given :

• Radius of Cylinder (r) = 7cm
• Height of Cylinder (h) = 15cm

To Find :

• Volume of Cylinder

Solution :

✰ As we know that, Volume of Cylinder is given by πr²h . Now in this question, Radius of Cylinder along with the Height of the Cylinder is given, So simply we will put the given values in the formula to find the Volume of the Cylinder.

⟶ Volume = πr²h

⟶ Volume = 22/7 × (7)² × 15

⟶ Volume = 22/7 × 7 × 7 × 15

⟶ Volume = 22 × 7 × 15

⟶ Volume = 154 × 15

⟶ Volume = 2310cm³

Thus, Volume of the Cylinder is 2310cm³
