WebIf you know the arc length and the radius, then the angle that is subtended by the sector is θ = L / r where L= arc length and r = radius (Angle in radians, of course.) Thus, the area of the sector would be: A = (θ / 2π) (π r²) A = ½ θ r² Now, we plug in the formula for θ A = ½ (L/r) r² A = ½ r L 1 comment ( 4 votes) Upvote Downvote Flag more WebArc length.
