Answer:
A, or 50.24 ft.
Step-by-step explanation:
Doing the equation above, we know the radius of the circle, which is 8 ft.
8ft times 2 is 16ft.
16ft times pi gives us (rounded) 50.24 ft.
U estimate 46.78 to 47 and 18.55 to 19, so 47-19 is 28.
Answer:
As a fraction it's ¼, as a decimal it's 0.25 and as a percentage it's 25%

Find f(6)
From the piecewise function, the value of f(x) is:

If 
And the value of f(x) is:

If 
In f(6), the value of x is 6 and 
So, we make use of

Substitute 6 for x
