In a certain ellipse, the endpoints of the major axis are (-11,4) and (9,4). Also, the ellipse passes through the point (7,7). Find the area of the ellipse.
The equation works out to (x + 1)^2/10^2 + (y - 4)^2/6^2 = 1, so the area of the ellipse is 60*pi.
I didn't get that answer.
The are of an ellipe is pi *a *b
Where a and be are the lengths of the semi-major and semi-minor axes,
