Question

a rectangular piece os paper 22×7cm is folded without overlapping to make a cylinder of height 4cm find the volume of cylinder
​

Answer 1

Answer:

154 cm³

Step-by-step explanation:

Rectangle:

Length of rectangle = 22 cm

Breadth of rectangle = 7 cm

As the rectangle sheet is folded to form a cylinder without overlapping,

Therefore circumference = length of rectangle

⇒ 2 π r = length

⇒ 2 * 22/7 * r = 22 cm

⇒ r = 7/2 cm = 3.5 cm

Cylinder:

radius of cylinder : 3.5 cm

height of cylinder = 4 cm

therefore volume of cylinder =  πr²h

⇒ 22/7 * 3.5 * 3.5 * 4 cm³

⇒ 154 cm³
