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 Web18. Think about how the cartesian variables x and y are bounded. If we have the equation. x 2 + y 2 = r 2 ⇒ x = ± r 2 − y 2 or y = ± r 2 − x 2. And x , y < r. Note that this last condition also insures that the above square roots are real. Then this gives you bounds for your double integral, choosing to integrate x first,
