Question

# The radius of the circle passing through the points of intersection of ellipse = 1 and x^{2 }– y^{2} = 0 is -

## The correct answer is:

### Two curves are symmetrical about both axes and intersect in four points, so, the circle through their points of intersection will have centre at origin.

Solving = 0 and = 1, we get

=

Therefore radius of circle

= =
