Talk:1999 AIME Problems/Problem 6

This solution is not accurate, as checking through a computer graphing program reveals the actual area of the parellelogram to be 300. A quick solution may involve finding the area of the circular sector and multiplying by $\frac{3}{\pi}$, though I am unsure how to find that reasoning without first knowing the answer. Another approach is coordinate bashing and attempting to find the altitude of the trapezoid, though this solution is excessively long with plenty of room for errors.
