Question

(G.11c, 1 point) The minute hand on a clock is 6 centimeters long and travels through an arc of 108° every 18 minutes. Calculate which measure is closest to the length of the arc the minute hand travels through during this 18 minute period? 1 12 11 10 1080 -9 2 3 8 4 7 6 5 O A. 3.67 cm O B. 10.87 cm C. 67 cm D. 127 cm

Answer 1

Let's find the Arc length:

`\begin{gathered} L=r\theta \\ \text{where:} \\ r=6 \\ \theta=108=(3)/(5)\pi \\ L=(6)((3)/(5)\pi)=3.6\pi cm \end{gathered}`
