The arc has a length of $1.88$ $1.88$ feet, approximately.

Explanation:

The formula for arc length of a circle is $s = θ r$ $color(magenta)(s = thetar$ , where $θ$ $theta$ is the central angle in radians, $r$ $r$ is the radius and $s$ $s$ is the arc.

We must convert $54˚$ to radians. We use the conversion factor $pi/180$ .

$54˚ xx pi/(180˚) = (3pi)/10$

Apply the above mentioned formula:

$s = theta xx r$

$s = (3pi)/10 xx 2$

$s = (3pi)/5$

$s ~= 1.88" "feet$

Hopefully this helps!
