Question

The circumference of a base of a cylinder is 220cm and height is 30cm. Find volume

Answer 1

Given,

• Circumference of a base of a cylinder is 220 cm.
• Height of a cylinder is 30 cm.

To Find,

• The volume of a cylinder.

According to question,

We know that,

Circumference of a cylinder = 2πr

[ Put the values ]

⇒ 220 = 2 × 3.14 × r

⇒ 220 = 6.28 × r

⇒ r = 220/6.28

⇒ r = 35 cm

Now,

We need to find the volume of a cylinder,

Volume of a cylinder = πr²h

[ Put the values ]

⇒ V = 3.14 × (35)² × 30

⇒ V = 3.14 × 1225 × 30

⇒ V = 3846.5 × 30

⇒ V = 115395 cm³

Therefore,

The volume of a cylinder is 115395 cm³.

Answer 2

Question :-

• The circumference of a base of a cylinder is 220cm and height is 30cm. Find volume

Answer :-

• volume of a cylinder is 115395 cm³.

Given -

• Circumference = 220 cm.
• Height of cylinder = 30 cm.

To Calculate :-

Find volume ?

So , let's find out radius

We know that :-

Circumference = 2πr

From given ,

↠ 220 = 2 × 3.14 × r

↠ 220 = 6.28 × r

↠ r = 220/6.28

↠ radius = 35 cm

Therefore ,

➤ Volume of a cylinder = πr²h

➤ Volume = 3.14 × (35)² × 30

↠ 3.14 × 1225 × 30

↠ 3846.5 × 30

= 115395 cm³

$Hence$ , volume of a cylinder is 115395 cm³.
