Question

What is the arc length of this sector? , and What is the arc length of this sector?

Answer 1

The arc length formula is given by:

`L=\theta\cdot r`

Where θ is the central angle and r is the radius. From the problem, we identify:

`\begin{gathered} \theta=(\pi)/(2) \\ \\ r=7\text{ m} \end{gathered}`

Then, using the formula:

`\begin{gathered} L=(\pi)/(2)\cdot7 \\ \\ \therefore L=(7\pi)/(2)\text{ m} \end{gathered}`
