5. What is the radius of a half-piece when it is cut as shown in the picture? (ie, where do I need to cut to make two equal halves out of a piece?)
I was told to use this formula, A = (n/360) * pi * r^2 but I don't know what n is... I know it's the central angle but I'm unsure how to find it!
Whoops sorry, I meant 30-60-90!
this is a 30-50-90 triangle by the way !
