What is the geometrical origin(meaning) of s/r=Thita​

Answer»

There is a formula that RELATES the arc LENGTH of a circle of RADIUS, r, to the central ANGLE, θ in RADIANS.

Formula for S=rθ

The picture below illustrates the relationship between the radius, and the central angle in radians. The formula is S=rθ where s represents the arc length, S=rθ represents the central angle in radians and r is the length of the radius.
