Answer: 8.37 cm rounded

Step-by-step explanation: The second hand on a clock rotates around the center of a clock creating a circle. This means it travels around the circle of the clock every hour. Its distance around the clock is the circumference of its circle with radius 8 cm.

This is the total distance around the clock in 1 hour. But how far does it travel in 10 minutes? 10 minutes is 1/6 of 60 minutes, a full hour. Multiply the circumference by 1/6 to find the distance in 10 minutes.

1/6 ( 50.24)= 8.37
