WebMay 26, 2024 · Finding the area of a shaded region in a circle can be tricky. We discuss many examples of finding areas of different types of shaded ... we can now substitute the value of arc length in the formula of the area of the sector. Afterwards, we can solve for the radius and central angle of the circle. $60 = \dfrac{\theta}{360^{o}}. r^{2 ... WebApr 11, 2024 · The sector area formula may be found by taking a proportion of a circle. The area of the sector is proportional to its angle, so knowing the circle area formula, we can write that: α / 360° = Sector Area / Circle Area. Angle conversion tells us that 360° = 2π. α / 2π = Sector Area / πr². so: Sector Area = r² × α / 2
