Question

The circumference of the circle shown below is 60 units. What is the approximate length of arc AB? Use π=3.14

Answer 1

$\text{length of arc = }\frac{\emptyset}{360}\times2\pi r$

Therefore,

$\begin{gathered} \emptyset=36^{\circ} \\ \text{length of arc=}\frac{36}{360}\times60=\frac{60}{10}=6\text{ units} \end{gathered}$
