As shown in the figure below, a circular park consists of an outer-ring path for walkers (white) and a ring-shaped flower garden (gray) surrounding a central circular fountain (black). The walking path is six feet wide in all places, the garden ring is eight feet wide in all places, and the fountain has a diameter of 10 feet. What is the diameter, in feet, of the circle that is the outer boundary of the walking path?

The radius of the outer ring is 5' + 8' + 6'  =  19'.

The circumference of the outer ring is:  C  =  2·pi·r  =  2·pi·19  =  119.38'.
