Erm , from your diagram , i guess W is the length of the chord . If so , we can apply this formula :
, We know the r and thus we can find
So now you have the angle .
Area of a segment =
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
