1.A circle is drawn with the two foci of an ellipse x2a2+y2b2=1\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1a2x2+b2y2=1 at the end of the diameter. What is the equation of the circle?a.x2+y2=a2+b2x^2 + y^2 = a^2 + b^2x2+y2=a2+b2b.x2+y2=a2−b2x^2 + y^2 = a^2 - b^2x2+y2=a2−b2c.x2+y2=2(a2+b2)x^2 + y^2 = 2(a^2 + b^2)x2+y2=2(a2+b2)d.x2+y2=2(a2−b2)x^2 + y^2 = 2(a^2 - b^2)x2+y2=2(a2−b2)Login to continueOnly logged in users canattempt or see the solution.
