Circumference theorem
WebPerimeter 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) Thus, the perimeter of the … WebIn this article, we learned about the sector of a circle, minor and major sector, the sector formula for area, perimeter and arc length with and without angle. Now, let us look at some solved examples and practice questions. Solved Examples On Sector of a Circle. Calculate the area of the sector. Solution: The radius of sector $= r = 6$ inches
