Hello!

How do i get the area of this segment on the top of the circle?

w=44.5 mm

h=10.35 mm

r=34.9 mm

I have found some formulas for calculating the area, but it seems like I need some angle.. ? What If i dont know the angle...?

A=0.5*r*(b-w)+w*h

b is the arc length, b = r*angle*pi/180

How do I use this angle?

I know that the answer should be approx 696 mm2 from a computer program, but I cant do it analytically...

Need help
