Please help!
I believe the mathematical calculations to determine the pie shaped triangles are a form of calculus equation. It's been 30+ years since I last sat in calculus class, but I'm fairly certain the parabolic arcs and shapes associated with them can be determined using integrals.

Unlike 30+ years ago when I took calculus, today the internet has calculators available to determine things like this:

Before anyone asks: Yes, the internet did exist when I was in college, I practically lived in the computer lab.
