Step 1
Let the radius of another circle =r
so according to the question
radius of a circle =2r
Step 2
area of another circle A=πr2
area of a circle =π(2r)2
=4πr2
ratio of the areas of circles
4πr2πr2=41
the ratio of the areas =41

I have encountered that in some cases maximization of a function had been substituted with a maximization of its monotone transformation.

For example, finding the min or max of f ( x , y ) = ( ( x 1 ) 2 + ( y 2 ) 2 ) 1 / 2 is the same as finding the min / max of ( x 2 + y 2 ) and then take the square root of the answer. So, my questions are:
1) Is it true for any monotone transformation g?
2) Is the same principle allow us to maximize /minimize log g ( x ) instead of g ( x ) itself?
