Radius of the sector
WebIf told to find the missing values of a sector with angle 58 degrees and chord of length 43, you can begin solving by finding the radius length. As stated above, if given an angle value … WebFind the radius of a sector whose area is 47 meters squared and central angle is 0.63 radians. Solution Area of a sector = (θ r2 )/2 47 = 0.63r 2 /2 Multiply both sides by 2. 94 = 0.63 r 2 Divide both sides by 0.63. r 2 =149.2 r = 12.22 So, the radius of the sector is 12.22 meters. Example 8
