Are of a circle segment

  1. 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

    Hello ladil123! :smile:

    Subtract the area of the triangle from the area of the sector. :wink:

    Add the segment to the obvious triangle, and you get a "piece of pie". :smile:
