GEOMETRY GURUS!!! Area of an Oval - SOLVE!

OK...here's the deal. Take a look at the image below. An oval (an oddball ellipse) is made up of four intersecting circles. The ONLY dimensions known are shown on the image. What forumla would be needed to find the area, or even the lenghth (on the Y axis) of the oval? Myself and my boss have beat ourselves up for the last 2 hours trying to figure this out.
Keep in mind that this is NOT a true ellipse. A true ellipse is easy to figure out Pi(R1*R2). This DOES NOT work in this scenario.
Let's see how smart the TAs truly are :)

| why do ppl come to the chillout room to do their homework...and they make it sound like theyre trying to test u to see how intelligent u are but really theyre just stuck on question 6 on page 5 |

hm, 4 intersecting circles...?
i'd say try to use calculus & integrals; maybe arclength, but it's not gonna be pretty. |

Nah Vivid, this is for when you are grocery shopping and they wont let you buy groceries because you cant do math, so if you wanna eat you have to solve confusing math probs| |

Actually, did you even read my post? I stated that my boss and I have spent about 2 hours trying to solve this and we are stumped....doesn't that say flat out that I don't know? I didn't think this was a test. I simply need the answer, and I'm out of resources...
Edit: And no...this isn't homework. Its actually job related. Regardless, I'm stumped! |

would you get the right answer if you just found the perimeter and changed it into a circle?
is this like something from that math test that's the hardest in the world and only has like 12 questions? cus it sure looks like it... i say there is no way you can really find it.. that's what i wanna say |

| looks like you did this in autocad or osmehting similar, can you find the area and just work backwards. |

No, this is not from that test. This is an actual scenario that I have encountered at work (I work IS/Programming for a glass manufacturing facility). We need to determine the actual yield of a particular shape when the piece of glass is cut.
We have pretty much decided, as well, that it may be impossible... |

no its not impossible
there has to be some equation behind it it.
can you give us a better picture of what your describing?
its hard for me to figure out what we have as a given |

It was done in AutoCad 2004, and even that program does not find the area of an oval. It will give us the length, but in our workplace, the length is an unknown value, because it is not necessary to actually know the length to draw the shape. |

| if you're the ones making the dimensions.. then where is the rest of the info? i mean.. damn.. this is like beyond a resonable level of difficulty for something you're actually able to physically deal with. |

eh it has been 2 years but I konw there is a way, I think if you pline the entire thing you can get stats on it that describe area. I forget teh actual commands btu I think I remember doing the same thing before.
Now I want to reinstall autocad...damn you. |
