Answer:

<u></u>

  • <u>a) 60π inches</u>

<u></u>

  • <u>b) 5π feet</u>

<u></u>

Explanation:

The <em>arc length</em> of a <em>circular </em>sector is related to the <em>swept angle</em> by the proportion:

       

        \dfrac{arc\text{ }length}{2\pi \cdot radius}=\dfrac{angle}{360\º}

Here you have:

  • arc length: ?
  • radius: 48 inches
  • angle: 225º

Substitute and solve for the arc length:

In inches:

       arc\text{ }length=\dfrac{225\º}{360\º}\times 2\pi (48in)}=60\pi   inches

Convert to feet:

Use the conversion factor: 1 feet = 12 inches

           60\pi\text{ }in\times\dfrac{1ft}{12in}=5\pi ft
