An ellipse is drawn with major and minor axis of length 10 and 8 respectively. Using one focus a centre, a circle is drawn that is tangent to ellipse, with no part of the circle being outside the ellipse. The radius of the circle is (A) sqrt3 (B) 2 (C) 2sqrt2 (D) sqrt5

The equation of the parabola whose vertex is at the centre of the ellipse x^2/25+y^2/16 = 1 and the focus coincide with the focus of the ellipse on the positive side of the major axis of the ellipse is

An ellipse is drawn with major and minor axis of length 10 and 8 respectively.Using one focus a centre,a circle is drawn that is tangent to ellipse,with no part of the circle being outside the ellipse.The radius of the circle is (A) sqrt(3)(B) (C) 2sqrt(2)(D)sqrt(5)

An ellipse is cutout of a circle of radius a,the major axis of the ellipse coincides with one of the diameter of the circle while the minor axis is equal to 2b .Prove that the area of the remaining part equals that of the ellipse with the semi axes a and a -b .

point 'O' is the centre of the ellipse with major axis AB & miror axis CD. Point F is one focus of the ellipse. If OF=6 & the diameter of the inscrided circle of triangle OCF is 2, then the products (AB) (CD) is

Point 'O' is the centre of the ellipse with major axis AB & minor axis CD. Point F is one focus of the ellipse. If OF = 6 & the diameter of the inscribed circle of triangle OCF is 2, then find the product (AB).(CD)
