Find the angle of a sector calculator
WebThe sum of the angle around a point is equal to 360° .. Therefore, the area of a sector is the fraction of the full circle’s area. The angle is out of 360 or \frac{\theta}{360} , where θ represents the angle, so we can multiply this by the area of the circle to calculate the area of a sector.. NOTE: At GCSE, all angles are measured in degrees. WebCalculates the area, circular arc and chord of a circular sector given the radius and angle. radius r angle θ degree radian area S circular arc L chord c
