WebApr 7, 2024 · Before you can use the Sector Area Formula, you will have to find the value of θ (the central angle that intercepts arc AB, which is the arc of the shaded region) and the length of the radius of circle K. You already know that the radius r is equal to 5. But what about θ ? ∠AKB and ∠AKC are supplementary WebA circle sector is a portion of a circle enclosed by two radii and an arc. The perimeter of a circle sector is the length of the two radii plus the length of the arc. The formula for finding the perimeter of a circle sector is: P = \pi *R* \dfrac {\alpha^o} {180^o} P = π ∗ R ∗ 180oαo Or P = 2R + \alpha *R P = 2R + α ∗ R
