WebA circle broken into seven sectors. Six of the sectors have a central angle measure of one radian and an arc length equal to length of the radius of a circle. The seventh sector is a smaller sector. The seven sectors represent the little more than six radians that it takes to make a complete turn around the center of a circle. WebJul 3, 2024 · The formula for finding the area of a sector is: A = (Sector Angle / 360) * (π * r^2) Using the example from slide No. 5, the radius is 4.5 inches, and the sector angle is 34 degree, you would have: A = 34 / 360 * (3.14 * 4.5^2) A = .094 * (63.585) Rounding to the nearest tenth yields: A = .1 * (63.6) A = 6.36 square inches
