Find the arc length of the partial circle.
Fither enter an exact answer in tom

Answer 1

50.265(correct to 5 significant figure)/ 16π

Explanation:

`\pi({8}^(2) )( (90degree)/(360degree) )`

`= \pi(64)( (1)/(4) )`

=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).
