Final answer:
The approximate length of arc s on a circle can be calculated using the formula: s = r * θ, where r is the radius of the circle and θ is the central angle in radians.
Step-by-step explanation:
The approximate length of arc s on a circle can be calculated using the formula:
s = r * θ
Where r is the radius of the circle and θ is the central angle in radians. To calculate the length of arc s, you need to know the value of the central angle and the radius of the circle.
