Question

7 ? Find the arc length of the partial circle. Either enter an exact answer in terms of or use 3.14 for 7 and enter your answer as a decimal.

Answer 1

The arc length is given by:

`\begin{gathered} L=r\theta \\ \text{Where:} \\ r=radius=7 \\ \theta=\text{angle (in radians)}=(\pi)/(2) \\ L=(7\pi)/(2)\approx10.99557429 \end{gathered}`
