Do you guys understand this question?

The equation defines a circle in x and y axis. How many integers are over that circle?

The possible answers are: 0, 4, 8, 10, 12

The answer is supposed to be 8 (??????)

also what you mean how many integers over that cirlce? do you mean inside? on x/y plane?

so x^2+y^2=10, so radius=sqrt(10) and circle center is origin

so I'd imagine -1,-2,-3,0,1,2,3 all fall into the circle, but that's only 7
