Question

Could you help me find the answer I’m stuck on this practice problem

Answer 1

Given:

The radius is 18ft.

The angle is

`(\pi)/(3)`

To find:

The length of the arc

Step-by-step explanation:

The angle in degrees is

`(\pi)/(3)*(180)/(\pi)=60^(\circ)`

Using the formula of the length of the arc is,

`\begin{gathered} s=(\theta)/(360)*2\pi r \\ s=(60)/(360)*2*(22)/(7)*18 \\ s=18.857 \\ s\approx18.9ft \end{gathered}`

Final answer:

The length of the arc is 18.9 ft.
