Answer:
8 cm
Step-by-step explanation:
The clock face is a circle with the second hand being a radius.
The tip of the hand over the 10 min period is an arc of the circle.
arc length = 2πr × fraction of circle
10 min = [tex]\frac{10}{60}[/tex] = [tex]\frac{1}{6}[/tex] of the circle, thus
arc length = 2π × 8 × [tex]\frac{1}{6}[/tex] ≈ 8 cm
