An ellipse is drawn by taking a diameter...

An ellipse is drawn by taking a diameter of the circle `(x""""1)^2+""y^2=""1` as its semiminor axis and a diameter of the circle `x^2+""(y""""2)^2=""4` as its semi-major axis. If the centre of the ellipse is the origin and its axes are the coordinate axes, then the equation of the ellipse is (1) `4x^2+""y^2=""4` (2) `x^2+""4y^2=""8` (3) `4x^2+""y^2=""8` (4) `x^2+""4y^2=""16`

A

`4x^(2)+y^(2)=4`

B

`x^(2)+4y^(2)=8`

C

`4x^(2)+y^(2)=8`

D

`x^(2)+4y^(2)=16`

An ellipse is drawn by taking a diameter of the circle (x – 1)^2 + y^2 = 1 , as its semi-minor axis and a diameter of the circle x^2 + (y – 2)^2 = 4 as its semi-major axis. If the centre of the ellipse is at the origin and its axes are the coordinate axes, then the equation of the ellipse is:

The ellipse x^2+""4y^2=""4 is inscribed in a rectangle aligned with the coordinate axes, which in turn is inscribed in another ellipse that passes through the point (4, 0). Then the equation of the ellipse is (1) x^2+""16 y^2=""16 (2) x^2+""12 y^2=""16 (3) 4x^2+""48 y^2=""48 (4) 4x^2+""64 y^2=""48
