Above is the picture in question. A circle is given, center (-2,4) and a point outside the circle (0,10) is shown. Asked to calculate the area of the quadrilateral ABCD, I figured that this kite has sides 2 (the radii of the circle) and 6 (the difference between (0,4) and (0,10)). How can I calculate the area of the kite?
(I tried calculating the diagonals and got rad40 for one of the diagonals, but cannot figure out how to calculate the other)
