WebIn arc definition, the degree of curve is the central angle angle subtended by one station of circular arc. This definition is used in highways. Using ratio and proportion, 1 s t a t i o n D = 2 π R 360 ∘. SI units (1 station = 20 m): 20 D = 2 π R 360 ∘. English system (1 station = 100 ft): 100 D = 2 π R 360 ∘. WebJan 8, 2024 · Calculate the arc length according to the formula above: L = r * θ = 15 * π/4 = 11.78 cm. Calculate the area of a sector: A = r² * θ / 2 = 15² * π/4 / 2 = 88.36 cm². You can also use the arc length calculator to find the central angle or the circle's radius. Simply input any two values into the appropriate boxes and watch it conducting ... ear wax strips
