Nuts? My good man, math is like reading the score of a beautiful rhapsody or a sonata so if you're nuts then we both belong in the same sanitarium! Love the stuff and am highly addicted................
Thanks, @Chrissy Cross . It's the one I plan to wear to the Royal Wedding. Strange, though, I haven't yet received my invitation. I hope it's not lost in the mail. I didn't understand Pi in grade school, either. Nor high school.
My two homeschool children went to an International Pi Day event in our town. They built Scribble Bots. They had a wonderful informative time.
A quick calculation of Pi is 22/7. I can remember Pi as 3.141592654, but usually round it to 3.1416 in my calculations. Hal

Frank, there is no formula for elliptical circumference...you just have to define the characteristics of the curve and solve it with differential calculus. Hal
@Hal Pollner For AREA, I would set up the ellipse centered on the X-Y plane, use one of it's quarters, and add together the areas of an infinite number of tiny near-rectangles, then multiply by four. But, that's INTEGRAL Calculus. For the life of me, I cannot recall working toward lengths of curve segments, enclosed or not. Frank
