Answer:

arc length = π/3 or 1.04

Explanation:

Circumference formula: dπ (where d is diameter)

The circumference is 6π.

Arc length formula: x/360 * C (where x is degree of central angle and C is circumference)

20/360 * 6π

simplify fraction for easier calculation

1/18 * 6π

simplify again

1/3π = approx. 1.04
