The Holly is stringing lights around the edge of the patio is 37.68 feet.
It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
A circular patio has a diameter of 12 feet.
Then the radius (r) will be
[tex]\rm r = \dfrac{diameter}{2}\\\\r = \dfrac{12}{2}\\\\r = 6[/tex]
Holly is stringing lights around the edge of the patio will be
[tex]\rm Circumference = 2 \pi r\\\\Circumference = 2*3.14 *6\\\\Circumference = 37.68 \ \ ft[/tex]
Thus, the Holly is stringing lights around the edge of the patio is 37.68 feet.
