area of the circle=pi*r^2 or (pi*d^2)/4
area of the sector=(theta/360)*pi*r^2 theta=central angle
or 1/2*l*r where l-length of the arc and r= radius
length of the arc=(theta/360)*2pi*r
area of the segment=area of the sector-area of the triangle
area of the triangle=1/2*base*height
area of the triangle=[s(s-a)(s-b)(s-c)]^1/2
where a,b and c are thesides and s=semiperimeter=(a+b+c)/2

ALL of 'em's a tall order. there're quite a few, some may be unsolved, and some may be unthought of, as yet. the other answerers' links might help you find a lot of 'em, though (but i didn't check, so assume no responsibility).
