~Hello There!~
The formula to find the area of a circle is:

We already know this answer, so we write it as:

We need to calculate the radius (r) from this so divide both sides by 

Square root this to get r
r = 3.949327085
The formula for circumference is 
(d is the diameter )
Double the radius to get the diameter:
d = 7.89865417
Multiply this value by
to get the answer
The circumference is 24.81435391
Hope This Helps You!
Good Luck :)
Have A Great Day ^_^

Answer:
your answer is C. 45-j= 27
Step-by-step explanation:
any problem with a equal sign is a equation.
The graph does not support his claim. The vertical scale does not start At 0 which distorts the percent of change.

Answer:
a (3,-1)
Step-by-step explanation:
The number that "completes the square" is the square of half the x-coefficient, (-6/2)^2 = 9. Rearranging the given function to include the square trinomial, we have ...
f(x) = x^2 -6x +9 -1 . . . . . . . here, we have 8 = 9 - 1
f(x) = (x -3)^2 -1 . . . . . . . . . . vertex form
Comparing this to the generic vertex form ...
f(x) = (x -h)^2 +k . . . . . . . vertex at (h, k)
we see that h=3 and k=-1.
The vertex is (h, k) = (3, -1).
