WebCalculate the radius of a circle whose arc length is 144 yards and arc angle is 3.665 radians. Solution. Arc length = r θ. 144 = 3.665r. Divide both sides by 3.665. 144/3.665 = r. r = … WebFeb 5, 2015 · The slope of the function will be f ′ ( x) = tan θ . Acording to basic trigonometry, the length of hypotenuse will be d x sec θ = d x 1 + tan 2 θ = 1 + ( f ′ ( x)) 2 d x . By integrating this, we can find out the arc length within any interval. ∫ x 1 x 2 1 + ( f ′ ( x)) 2 d x Share Cite Follow edited Feb 5, 2015 at 17:33
WebOct 20, 2015 · Start by using the half angle ψ that spans the arc Note that tan ψ = x / 2 d e p t h. I also used a dimensionless parameter for the shape equal to ϵ = h w 2 − h 2 where w is the known width and h is the known height. This created the arc length integral as ℓ = ∫ 0 ψ / 2 w 2 − ( w 2 − h 2) cos 2 ψ d ψ ℓ = w 1 + ϵ 2 ∫ 0 ψ / 2 ϵ 2 + sin 2 ψ d ψ WebApr 9, 2024 · In this video, we look at how to calculate the arc length of a sector of a circle using ang...
