(pardon the first two posts--I wrote 390 degrees instead of 360)
Greetings. I need a geometry expert, please.
I have an 8 inch, 360 degree, chimney pipe coming into my basement at a 45 degree angle. I need to cut out a tin heat shield that lays flat against the wall, around the pipe. Obviously, it would be "eliptical-ish" (my word), but I wonder what the equation for this would be?
Thanks very much
