Question

# A Rectangular sheet of paper 44 cm x 18 cm is rolled along its length and a cylinder is formed. What is the volume of the cylinder so formed?

Hint:

### If a rectangular sheet of paper is rolled along its length to form a cylinder, then its length becomes the circumference of the cylinder base and its width becomes the height of the cylinder.

## The correct answer is: The volume of the cylinder so formed is 2772 cm3.

### Explanations:

Step 1 of 3:

The length and width of a rectangular sheet of paper are given by, 44 cm and 18 cm, respectively.

As per the hint, if the paper is rolled along its length to form a cylinder, then the height of the cylinder would be 18 cm(= *h*), and the circumference of the cylinder base would be 44 cm.

Step 2 of 3:

Therefore, cm

The radius of the cylinder formed is 7 cm(= *r*).

Step 3 of 3:

The volume of the formed cylinder is cm^{3}

Final Answer:

The volume of the cylinder so formed is 2772 cm^{3}.

( 1 kilogram = 2.2046 pounds)

**Note:**

There are many other units of weight such as ton, ounce, gram, stone, grain, milligram, etc. There is conversion formula for each of these pairs, for eg.

1 kilogram = 35.27 ounce= 0.16 stone= 1000 gram

1 pound= 16 ounce= 0.07 stone= 435.60 gram
