2 answers:
Answer: 25.12 ft.
Step-by-step explanation:
Given: The diameter of circle d= 8 ft.
We know that the circumference of a circle is given by the formula:-
Hence, the exact circumference of a circle with diameter equal to 8 ft is 25.12 ft.
The circumference of the circle is the linear length of the circle if the arcs are laid linearly. In this case, the formula that must be followed is C = pi D where C is the circumference and D is the diameter. The circumference then is equal to 8 pi ft

Answer:
y-4=-2(x+1)
Step-by-step explanation:
y-y1=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(-4-4)/(3-(-1))
m=-8/(3+1)
m=-8/4
m=-2
y-4=-2(x-(-1))
y-4=-2(x+1)
