Determine arc length from radius and angle
WebJun 14, 2024 · Find the arc length along a circle of radius 10 units subtended by an angle of 215°. ... In addition to arc length, we can also use angles to find the area of a sector of a circle. A sector is a region of a circle bounded by two radii and the intercepted arc, like a slice of pizza or pie. Recall that the area of a circle with radius \(r\) can ... Webθ1 = θ2. We will prove this theorem below. Example 1. ;If s is 4 cm, and r is 5 cm, then the number , i.e. is the radian measure of the central angle. At that central angle, the arc is four fifths of the radius. Example 2. An angle of .75 radians means that the arc is three fourths of the radius. s = .75 r. Example 3.
