Find the circumference of the circle.
A. 50.24 feet
B. 12.56
C. 6.28
D. 25.12
I believe it’s

Option D, 25.12

Step-by-step explanation:

The formula to find the Circumference is:  C = 2πr

Step 1:  Plug in

C = 2πr

C = 2π(4)

C = 8π

C = 25.13

 Option D, 25.12

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

yes. we do proportions in probabilities.
