Question

Find the volume of a cylinder whose radius is 14cm and height is 20cm.​

Answer 1

Answer:

The volume of a cylinder is 12320 cm³

Explanation:

Given :

• Radius of cylinder (r) = 14 cm

• Height of cylinder (h) = 20 cm

Find :

• The volume of a cylinder

Solution :

★ As we know that

Formula of volume of a cylinder

Volume of cylinder = π r² h

⇒ 22 / 7 × 14² × 20

⇒ 22 /7 × 196 × 20

⇒ 22 × 28 × 20

⇒ 12320 cm³

Therefore ,

The volume of a cylinder is 12320 cm³

Answer 2

⚘ Given :-

• Radius Of Cylinder = 14cm.

• Height Of Cylinder = 20cm.

⚘ To Find :-

• Volume Of Cylinder.

⚘ Solution :-

Formula For Finding Volume :- πr²h.

Put Their Values.

Note :- We will take π as 22/7 as any another value is not given.

➝ 22/7 × 14² × 20.

➝ 22/7 × 14 × 14 × 20.

➝ 22 × 2 × 14 × 20.

➝ 22 × 28 × 20.

➝ 12320 cm²

Hence, Volume Of Cylinder = 12320 cm².
