I might as well start with a question for people to attempt.

you have to somehow get 1/2 x base = (r + square root of r^2 - x^2)

hmmm... i'm working on it...

1/2B = x (so that's done)
to find the vertical height:
rotate r to make it horizontal the ad r + y which is the formula of the circle
there for h = (r + sq. root r^2 - x^2)
if you get what i mean

Uh yeah? It's maximum/minimum (2U course)
Wow I really love that question, very unique in someway. Is there any chance that I could save her for you? No terms and conditions applied :)

r is just the radius. So the height of the triangle is just r+y, and use pythagoras to find y, and then the solution falls out straight away.

You made this question? It's very nice imo. I might come up with one of my own soon.
