Question

7.
A rectangular sheet of paper is rolled along its length to make a cylinder. The
sheet is 33 cm long and 32 cm wide. A circular sheet of paper is attached to the
bottom of the cylinder formed. Find the capacity of cylinder so formed.​

Answer 1

Answer:

Pls mark me brainliest

Step-by-step explanation:

Given : Length of the rectangular sheet = 33 cm

And, Width of the rectangular sheet = 32 cm

As we know that,

length of the rectangular sheet  = circumference of the circle

Circumference of the circle = 2πr

⇒ 33 cm = 2*22/7*r

⇒ r = (33*7)/(22*2)

⇒ r = 231/44

⇒ r = 5.25 cm

Capacity or volume of the cylinder = πr²h

⇒ 22/7*5.25*5.25*32

⇒ 22/7*27.5625*32

⇒ 19404/7

⇒ 2772 cm³

Hence, the capacity or the volume of the cylinder is 2772 cm³.

Answer 2

Solution :-

Given : Length of the rectangular sheet = 33 cm

And, Width of the rectangular sheet = 32 cm

As we know that,

length of the rectangular sheet = circumference of the circle

Circumference of the circle = 2πr

⇒ 33 cm = 2*22/7*r

⇒ r = (33*7)/(22*2)

⇒ r = 231/44

⇒ r = 5.25 cm

Capacity or volume of the cylinder = πr²h

⇒ 22/7*5.25*5.25*32

⇒ 22/7*27.5625*32

⇒ 19404/7

⇒ 2772 cm³

Hence, the capacity or the volume of the cylinder is 2772 cm³.
