You know that th 120 since it is given that angle KPL equals 120 degrees. Once you got the hang of radians we can use the arc measure formula which requires the arc length s s and the radius of the circle r r to calculate. In this case to find the total circumference.
Once you got the hang of radians we can use the arc measure formula which requires the arc length s s and the radius of the circle r r to calculate.
Hence as the proportion between angle and arc length is constant we can say that. I wonder why the function has to have continuous derivative According to the Stewart Calculus book. Arc length R C. The length more precisely arc length of an arc of a circle with radius r and subtending an angle th measured in radians with the circle center ie the central angle is.
