To find the length of the arc intercepted by the central angle, you can use the formula
, where
is the arc length,
is the radius, and
is the angle in radians. Substituting the values, we get
feet.
Now, converting the angle from radians to degrees involves the formula
. Thus,
.
Finally, to find the circumference of the circle, use the formula
