The second hand on the clock pictured below is 6 cm long. How far in centimeters does the tip of this second hand travel during a period of 30 minutes? Express your answer in terms of pi.
The equation for circumference is πd and the so the circumference of the circle formed by the second hand is 12π. In 30 minutes, the second hand will travel around the clock 30 times, 1 per minute. This gives us the equation 12π * 30 = 360π cm.
