The Math Behind the Fact: One way to see why the formula is true is to realize that the above ellipse is just a unit circle that has been stretched by a factor A in the x-direction, and a factor B in the y-direction. Hence the area of the ellipse is just A*B times the area of the unit circle. First and foremost, you should understand that the ACT ® Math test contains a formula sheet, which displays formulas relating to geometric measurement and certain algebra concepts. Formulas are provided to test-takers so that they may focus on application , rather than the memorization , of formulas.
