If the base of the triangle is the line for the arch, 24
half of the base is 12
in half of the angle of the arc
12/20 = 0.6 and is at an angle of 37 °
twice at 37 º = 74 º
360 º / 74 º = 4,86
Area of circle = 3.14 (20) ² = 1256
1256/4.86 = 258.44 units ²
The area of the segment with the above description as
Square is 258.44 units.
I need to know the angle of the segment.
In one segment, the parties have exactly the same length as the radius of the circle.
The formula is:
1/2r ² (π/180θ-sinθ)
What exactly is the area shaded in blue? Need a photo or at least more information.
