Question

A rectangular sheet of paper is having measures 11cm ×4 cm and it is folded without overlapping to make a cylinder of height 4 cm ​

Answer 1

Answer:

Given:

A paper measures 11 cm by 4 cm,

It is folded to make a cylinder,

It has a height of 4 cm,

To Find:

Volume of the cylinder,

Explanation:

When the paper is folded, the length, 11 cm, will become the circumference of the cylinder

Solution:

Find the radius:

circumference = 2πr,

2πr = 11,

r = 11 ÷ 2π,

r = 1.75 cm,

Find the volume:

Volume = πr²h,

Volume = π(1.75)²(4),

Volume = 38.5 cm³,

Answer: The volume is 38.5 cm³,

Hope it helps.
