Jul 30, 2024 · The length of an arc depends on the radius of a circle and the central angle θ. We know that for the angle equal to 360 degrees (2π), the arc length is equal to circumference. Hence, as the proportion between angle and arc length is constant, we can say that: L / θ = C / 2π. As circumference C = 2πr, L / θ = 2πr / 2π. L / θ = r
Suppose we have an arc with an arc length of 8 units and a central angle of 45 degrees. Step 1: Convert the angle to radians. θ = 45° = 45 * π 180 = π 4. Step 2: Plug the given values into the formula and simplify the equation. r = 8 π / 4 ≈ 10.186 units.
The length of the arc depends on the angle it forms. The proportion of the arc in the entire circumference corresponds to the proportion of the angle in 360° (the entire circle). The formula for calculating the arc of a circle is: l = 2 ⋅π ⋅r ⋅ α 360 l = 2 · π · r · α 360. Where α is the angle in degrees and r is the radius of ...
