Beat you to it! (EDIT: This was addressed to NewAccount - I’m too slow)

This is why I really don’t like memorizing the final formulas. If you put pi/2 instead of pi/8, or sqrt(3)/2 instead of sqrt(3)/4 (how did you make the sqrt sign?), you get it all wrong. But if you work it from the beginning, your final formula is usually right. (However, if you have a greater chance of messing up by working the area equation out instead of memorizing it, then by all means memorize. Just do what’s easiest for you)
