Chapter 0.7, Problem 15E

To determine

To calculate: the total distance travelled in ten rotations.

Answer to Problem 15E

  $\text{848}\text{.2 in}\text{.}$

Explanation of Solution

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

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

  $\begin{array}{l}\text{Distance}=10\pi (27)\\ \text{Distance}=270\pi \\ \text{Distance}=848.23\approx 848.2\end{array}$
