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*(bw)+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

Hello ladil123!
Subtract the area of the triangle from the area of the sector.
