Answer:

The arc's length is 1.8 ft

Explanation:

For calcaulate the arc length S we used the formula below:

$S=(\pi.\alpha(\º))/(180)*R$

Here alpha is the arc angle in degrees and R is the circle radius. Thus, if alpha is equal to 26 and R equals to 4 ft:

$S=(\pi.26)/(180)\ *\ 4ft$

$S=0.45\ *\ 4ft$

$S=1.8\ ft$
