The circumference of a clock is 44 inches. find the length of the minute hand on the clock. use 22 7 to approximate pi.
Answers: 1
of the clock. 
![\bf \textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ C=44 \end{cases}\implies 44=2\pi r\implies \cfrac{44}{2\pi }=r\implies \cfrac{22}{\pi }=r \\\\\\ \stackrel{\textit{using }\pi =\frac{22}{7}}{\cfrac{~~22~~}{\frac{22}{7}}=r}\implies \cfrac{22}{1}\cdot \cfrac{7}{22}=r\implies \cfrac{22}{22}\cdot \cfrac{7}{1}=r\implies 7=r](/tpl/images/0081/8842/496d9.png)
