or repeating decimal numbers are the rational numbers.
Examples : 1, 2, 
Irrational numbers:
Numbers which can't be written in he form of a fraction or non repeating decimal numbers are the Irrational number.
Example: 
From the given numbers,
Rational numbers:
, 6.25, 0.01045,
, 0.424242....
Irrational numbers: 
The volume of the original cylinder is
... V = π·r²·h
For r=1 and h=1, this is
... V = π·1²·1 = π
For the new cylinder, the volume is 1.089 times that amount.
... V = 1.089π = π·1.1²·(1-k)
... 1.089/1.21 = 1-k
... k = 1 - 1.089/1.21 = 1 - 0.9 = 0.1 = 10%
The appropriate choice is (B) 10.
