how did u get that

anonymous · Answer

Cul-de-sac is a semicircle or half of a circle
Circumference (perimeter) of a circle is: diameter * Pi
So diameter of this circle is 52*3.14
But we only want half of it so (52*3.14)/2
Plus the 52 feet to across the ends of the semicircle.

a cul-de-sac is pretty much a dead-end road.  The problem indicates its circular tho, not semi-circular

so would you work out the problem and what is the formula you use
