Final answer:
The arc length is found using the formula s = rθ, where in this case r is 1 and θ is 4π/3 radians. Simplifying, we find that the approximate arc length is 4.18879.
Step-by-step explanation:
To calculate the arc length, we can use the formula s = rθ, where 's' represents the arc length, 'r' is the radius of the circular path, and 'θ' is the central angle in radians. In this case, we know that r = 1 and 'θ' (represented as 0 with a slash through it) is 4π/3 radians. Substituting these values into the formula, we get:
s = (1) × (4π/3) = 4π/3.
Since π is approximately 3.14159, the arc length s is approximately 4 × 3.14159 / 3, which simplifies to 4.18879 (rounded to 5 decimal places).
