A bug

A bug was sitting on the tip of a wind turbine blade that was 24 inches long when it started to rotate. The bug held on for 5 rotations before flying away. How far did the bug travel before it flew off? Exact answer.

Correct result:

s =  753.9822 inch

Solution:

$$\begin{gathered} a=24\text{ inch } \\ n=5 \\ o=2\pi \cdot a=2\cdot 3.1416\cdot 24\doteq 150.7964\text{ inch } \\ s=n\cdot o=5\cdot 150.7964=753.9822\text{ inch} \end{gathered}$$
