If you know the radius: Convert the central angle into radians: α [rad] = α [deg] · π/180° Multiplythe radius by the angle in radians. …
WebOct 1, 2024 · The perimeter is 40 cm, let's call it P. Let's call the arc length of the portion of the circle s. Then we have P = r + r + s = 2 r + s = 40 One thing we will use is the formula … WebThe formula that is used to find the perimeter of a sector is, Perimeter of sector = Radius + Radius + Arc length. Here, if the arc length is not known, it can be calculated with the formula, Arc length = r × θ; (where r = radius and θ = angle of the sector in radians).
WebApr 1, 2024 · The formula for the area of a sector is (angle / 360) x π x radius2. The figure below illustrates the measurement: As you can easily see, it is quite similar to that of a circle, but modified to account for the fact that a sector is just a part of a circle. WebFind the perimeter of a sector of a circle with central angle (7π)/4 and radius 3 ft. Note: I got (21π)/4 feet, but I'm not sure if it is correct. This problem has been solved!
