To determine

To calculate: the perimeter of given figure.

Answer to Problem 11E

  $31.4\text{ in}\text{.}$

Explanation of Solution

Perimeter is the total length of the boundary in the figure. The perimeter of the circle is:

  $P_{\text{circle}}=(2\pi r)or(\pi d)$

  $\begin{array}{l}{P}_{\text{circle}}=\pi (10)\\ P_{\text{circle}}=10\pi \\ P_{\text{circle}}=31.415\approx 31.4\end{array}$
