Answer:
50.265(correct to 5 significant figure)/ 16π
Step-by-step explanation:
[tex]\pi({8}^{2} )( \frac{90degree}{360degree} )[/tex]
[tex] = \pi(64)( \frac{1}{4} )[/tex]
=50.265(cor. to 5 sig.fig.)/ 16π
to find the arc length of a sector,we need to use πradius² times (sector's degree divided by 360degree).
