A) 1
B) 2
C) 4
D) infinite
Correct Answer: C
Solution :
Point (a, b) must lie on the director circle \[{{x}^{2}}+{{y}^{2}}=16\] \[\left( \frac{\sum\limits_{r=1}^{n}{8{{r}^{3}}}}{\sum\limits_{r=1}^{n}{27{{r}^{3}}}} \right)\,={{\left( \frac{8}{27} \right)}^{1/3}}\,=\frac{2}{3}\] Number of points (a, b) on the circle whose abscissa and ordinate both are integers are 4 i.e. (4, 0) (0, 4) (-4, 0) (0, -4).You need to login to perform this action.
