Question

the circumference of the base of a cylindrical vessel is 132 cm and its height is 25 cm how much litre of water can it hold (1000cm³=1 liter)​​

Answer 1

Answer:

Step-by-step explanation:

Given, 2πr = 132, h = 25 cm

2 x 22/7 x r = 132

132 x 7 / 44 = r

924/44 = r

∴ r = 21 cm

Volume  = πr²h

= 22/7 x 21 x 21 x 25 = 22 x 3 x 21 x 25

= 34,650 cm³

=34.65 l

∴ The vessel can hold 34.65l of water

Answer 2

Given

• Circumference of the base of a cylindrical vessel is 132 cm and its height is 25 cm.

We Find

• How much litre of water can hold per 1000 CM ³ = 1

We know that

2πr = 132 and height = 25 cm

= 2πr = 132

= 2 × 22/7 × r = 132

= 44/7 × r = 132

r = 132 × 44/7

Radius = 21 cm

So, Radius = 21 cm

According to the question

Volume of Hemisphere = 2/3 πr³

= 2/3 × 22/7 × 21³

= 2/3 × 22/7 × 21 × 21 × 21

= 44 × 441

= 19404 cm³

We convert into litre ( 1000 cm³ per litre )

= Volume of Hemisphere / 1000

= 19404 / 1000

= 19.404 Litre

So, 19.404 Litre is can hold it.
