Calculate the length of an arc of a circle that corresponds to a center angle of 60 degrees if the radius of the circle is 3m.
| November 18, 2020 | education
The length of a circular arc is determined by the formula l = π * r * n / 180, where r is the radius of the circle, n is the central angle corresponding to this arc.
By condition, r = 3 m, n = 60 °.
The required arc length: l = π * 3 * 60/180 = π, which is approximately 3.14 m.
