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 
cm3
Final Answer:
The volume of the cylinder so formed is 2772 cm3.

The load capacity of a certain washing machine is 12 pounds. What is the approximate load capacity of the same washing machine, in kilograms?
( 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
