Answer
The circumference of the circle is 59.7 ft
Step-by-step explanation
The diameter of the circle = 19ft
The circumference of a circle = 2 x pi x r
Where r = radius
Radius = Diameter / 2
Radius = 19 / 2
Radius = 9.5 ft
Circumference = 2 x pi x r
pi = 3.14
Circumference = 2 x 3.14 x 9.5
Circumference = 59.7 ft
Therefore, the circumference of the circle is 59.7 ft
