The center of the circle below is at P If the angle lt APB measures 48 and the radius is 8 cm find the length of the arc AB in cm round to the nearest tenth class=

Respuesta :

The length of the arc AB is given by:

[tex]\begin{gathered} arcAB=2\pi\cdot\frac{(\angle APB)}{360\degree}\cdot r \\ arcAB=2\pi\cdot\frac{48\degree}{360\degree}\cdot8 \\ arcAB\approx6.7\text{ cm} \end{gathered}[/tex]

Answer: a. 6.7 cm
