The radius of a circle = 39.11 m.
A radian exists as the angle subtended by an arc of length equivalent to the radius of the circle. ( "Subtended" indicates made by merging two lines from the endpoints of the arc to the center). An arc of length R where R stands for the radius of a circle equals an angle of 1 radian.
Length of arc = rθ
where r = radius,
θ = angle in radians.
57.1 = r [tex]*[/tex] 1.46
1.46r = 57.1
r = 39.1095
Radius ≈ 39.11 m
Therefore, the radius of a circle = 39.11 m.
