its D. i know for sure. if you need anything else let me know.
ANSWER
8π ft
EXPLANATION
The circumference of a circle is calculated using the formula C=πd.
Where d=8 is the diameter of the circle.
We substitute d=8 into the formula to obtain,
C=8π ft.
Because we are looking for the exact circumference, we leave the answer in terms of π.

Answer:
![(g\cdot f) = -3x^2-3](https://tex.z-dn.net/?f=%28g%5Ccdot%20f%29%20%3D%20%20-3x%5E2-3)
Step-by-step explanation:
![f(x) = x^2 + 1](https://tex.z-dn.net/?f=f%28x%29%20%3D%20x%5E2%20%2B%201)
![g(x) = -3](https://tex.z-dn.net/?f=g%28x%29%20%3D%20-3)
The problem state to multiply the function
and
so the symbol seems to be incorrect.
We actually want to calculate
![g(x) f(x) =gf(x) = (-3) \cdot (x^2+1)= -3x^2-3](https://tex.z-dn.net/?f=g%28x%29%20%20f%28x%29%20%3Dgf%28x%29%20%3D%20%20%28-3%29%20%20%5Ccdot%20%28x%5E2%2B1%29%3D%20-3x%5E2-3)
Note
![g\circ f(x)=g(f(x))=g(x^2+1)=-3](https://tex.z-dn.net/?f=g%5Ccirc%20f%28x%29%3Dg%28f%28x%29%29%3Dg%28x%5E2%2B1%29%3D-3)
Rule: multiply by -3
1) 1
2) -3
3) 9
4) -27
5) 81
6) -243
7) 729
8) -2,187
9) 6,561
The answer is A) 6,561
