What is the radius of the circle?

Actually This question was Given To me By My Freind And He is So cruel and Doesn't Give any Information for radius .

If the question means asks to find the number of rational points ( assuming it means points whose coordinates are rational numbers ) " enclosed " by the circle i.e., the union of set of points within the circle and on the circle it would strongly depend upon radius and I feel there would not be any nice looking formula for the same. If the questions demands to find the points lying "on" the circle then Ronak's argument seems quite valid.

yeah Thanks a ton , Now I got it !

If the radius of the circle not given then there is at most one rational point, since your arbitarily choose a point like (3,5) and hence decide the radius of the circle but then you will not get another rational point.

Could You Please Explain More , It sound's Interesting !

And If Radius is fixed Then ? @Ronak Agarwal

- 2 years, 10 months ago

My argument works for only the points lying on the circle. For finding the number of points enclosed by the circle it is impossible to find it without knowing the radius.

Yes I understand , My cruel friend tell me Poorly , Instead of This He should ask number of points Lies on Circle , which is 1 as You Explained betterly ! And Thanks for Replying :)

AITS-2 Percentage =56.11 %

AITS-3 Percentage = Yet to be known.
