49.71666... round to where you need to. I might be wrong. The formula should  be ArcLength = angle / 360 * 2 pi radius so 150/360*(2*pi*19)

Answer: 49.72 feet (approximate to 2 decimal places; using pi = 3.14)

=============================================================

Explanation:

The distance around the entire circle (also known as the circumference) is found by the formula

C = 2*pi*r

with C being the circumference, pi = 3.14 approximately, and r is the radius. The circumference of this circle is approximately C = 119.32 because C = 2*pi*r = 2*3.14*19 = 119.32

---------

The arc length is the shaded darker region of the circle's edge marked by the 150 degree central angle. We only want a portion of the entire distance around the circle. So we take a fraction of the circumference to get (150/360)*C = (150/360)*119.32 = 49.71667 = 49.72 which is approximate to two decimal places.

The Unknotting Problem: It the algorithmic recognition of the unknot that can be achieved from a knot. It defined the algorithm that can be used between the unknot and knot representation of a closely looped rope.

The Large Cardinal Project: it says that infinite sets come in different sizes and they are represented with Hebrew letter aleph. Also, these sets are named based on their sizes. Naming starts from small-0 and further, prefixed aleph before them. eg: aleph-zero.
