WebWe know that the segment of a circle is made up of an arc and a chord of the circle. Consider the same segment as in the above figure. Perimeter of the segment = length of the arc + length of the chord. We know that, the length of the arc is rθ, if 'θ' is in radians and πrθ/180, if 'θ' is in degrees. the length of the chord = 2r sin (θ/2) Web16 mrt. 2024 · Linear velocity is measured in linear units divided my time units, such as meters per second. Angular velocity ω is measured in radians/second or degrees/second.
