Respuesta :

Given data:

Diameter = 14 inches

Radius = diameter / 2

= 14 / 2

= 7 inches

Length of an arc PAQ,

[tex]l=r\theta[/tex]

Here, r = 7

[tex]l=7\times45^{\circ}[/tex][tex]\begin{gathered} l=\frac{135^{\circ}}{360}\times2\pi r \\ =\frac{\text{ 135}}{360}\times2\times3.14\times7 \\ =38.5 \end{gathered}[/tex]

Thus, the length is 38.5 inches
